I don’t want your data

This article is a repost promoting content originally published elsewhere. See more things Dan's reposted.

The web loves data. Data about you. Data about who you are, about what you do, what you love doing, what you love eating.

…

I, on the other end, couldn’t care less about your data. I don’t run analytics on this website. I don’t care which articles you read, I don’t care if you read them. I don’t care about which post is the most read or the most clicked. I don’t A/B test, I don’t try to overthink my content. I just don’t care.

Manuel Moreale

Manu speaks my mind. Among the many hacks I’ve made to this site, I actively try not to invade on your privacy by collecting analytics, and I try not to let others to so either!

My blog is for myself first and foremost (if you enjoy it too, that’s just a bonus). This leads to two conclusions:

If I’m the primary audience, I don’t need analytics (because I know who I am), and
I don’t want to be targeted by invasive analytics (and use browser extensions to block them, e.g. I by-default block all third-party scripts, delete cookies from non-allowlisted domains 15 seconds after navigating away from sites, etc.); so I’d prefer them not to be on a site for which I’m the primary audience!

I’ve gone into more detail about this on my privacy page and hinted at it on my colophon. But I don’t know if anybody ever reads either of those pages, of course!

Wacom drawing tablets track the name of every application that you open

I don’t care whether anything materially bad will or won’t happen as a consequence of Wacom taking this data from me. I simply resent the fact that they’re doing it.

The second is that we can also come up with scenarios that involve real harms. Maybe the very existence of a program is secret or sensitive information. What if a Wacom employee suddenly starts seeing entries spring up for “Half Life 3 Test Build”? Obviously I don’t care about the secrecy of Valve’s new games, but I assume that Valve does.

We can get more subtle. I personally use Google Analytics to track visitors to my website. I do feel bad about this, but I’ve got to get my self-esteem from somewhere. Google Analytics has a “User Explorer” tool, in which you can zoom in on the activity of a specific user. Suppose that someone at Wacom “fingerprints” a target person that they knew in real life by seeing that this person uses a very particular combination of applications. The Wacom employee then uses this fingerprint to find the person in the “User Explorer” tool. Finally the Wacom employee sees that their target also uses “LivingWith: Cancer Support”.

Remember, this information is coming from a device that is essentially a mouse.

Interesting deep-dive investigation into the (immoral, grey-area illegal) data mining being done by Wacom when you install the drivers for their tablets. Horrifying, but you’ve got to remember that Wacom are unlikely to be a unique case. I had a falling out with Razer the other year when they started bundling spyware into the drivers for their keyboards and locking-out existing and new customers from advanced features unless they consented to data harvesting.

I’m becoming increasingly concerned by the normalisation of surveillance capitalism: between modern peripherals and the Internet of Things, we’re “willingly” surrendering more of our personal lives than ever before. If you haven’t seen it, I’d also thoroughly recommend Data, the latest video from Philosophy Tube (of which I’ve sung the praises before).

Third party

This article is a repost promoting content originally published elsewhere. See more things Dan's reposted.

…why would cookies ever need to work across domains? Authentication, shopping carts and all that good stuff can happen on the same domain. Third-party cookies, on the other hand, seem custom made for tracking and frankly, not much else.

…

Then there’s third-party JavaScript.

In retrospect, it seems unbelievable that third-party JavaScript is even possible. I mean, putting arbitrary code—that can then inject even more arbitrary code—onto your website? That seems like a security nightmare!

I imagine if JavaScript were being specced today, it would almost certainly be restricted to the same origin by default.

…

Jeremy Keith

Jeremy hits the nail on the head with third-party cookies and Javascript: if the Web were invented today, there’s no way that these potentially privacy and security-undermining features would be on by default, globally. I’m not sure that they’d be universally blocked at the browser level as Jeremy suggests, though: the Web has always been about empowering developers, acting as a playground for experimentation, and third-party stuff does provide benefits: sharing a login across multiple subdomains, for example (which in turn can exist as a security feature, if different authors get permission to add content to those subdomains).

Instead, then, I imagine that a Web re-invented today would treat third-party content a little like we treat CORS or we’re beginning to treat resource types specified by Content-Security-Policy and Feature-Policy headers. That is, website owners would need to “opt-in” to which third-party domains could be trusted to provide content, perhaps subdivided into scripts and cookies. This wouldn’t prohibit trackers, but it would make their use less of an assumed-default (develolpers would have to truly think about the implications of what they were enabling) and more transparent: it’d be very easy for a browser to list (and optionally block, sandbox, or anonymise) third-party trackers could potentially target them, on a given site, without having to first evaluate any scripts and their sources.

I was recently inspired by Dave Rupert to remove Google Analytics from this blog. For a while, there’ll have been no third-party scripts being delivered on this site at all, except through iframes (for video embedding etc., which is different anyway because there’s significantly less scope leak). Recently, I’ve been experimenting with Jetpack because I get it for free through my new employer, but I’m always looking for ways to improve how well my site “stands alone”: you can block all third-party resources and this site should still work just fine (I wonder if I can add a feature to my service worker to allow visitors to control exactly what third party content they’re exposed to?).

Goodbye Google Analytics, Hello Fathom

This article is a repost promoting content originally published elsewhere. See more things Dan's reposted.

Big news! This site is no longer using Google Analytics and I’ve switched to a self-hosted version of brand new analytics product Fathom.

Fathom is very simple. It only tracks 4 things: Unique Visitors, Page Views, Time on Site, and Bounce Rate. It shows me a chart of page views and visitors and then gives me a break down of referrers and top performing content. That’s it. And to be quite honest, that’s about all I need from my blog analytics.

…

Dave Rupert

You know what, Dave:me too! I’ve been running Google Analytics since forever and Piwik/Matomo (in parallel with it) for about a year and honestly: I get more than enough of what I need from the latter. So you’ve inspired me to cut the line with Google: after all, all I was doing was selling them my friends’ data in exchange for some analytics I wasn’t really paying attention to… and I’d frankly rather not.

So: for the first time in a decade or so, there’s no Google Analytics on this site. Woop!

Update 2023-12-13: I eventually went further still and dropped all analytics, even self-hosted variants, and it feels great.

Minimal Analytics

This is cute: a Google Analytics code snippet that results in a payload about a fiftieth of the size of the one provided by Google but still provides most of the important features.
