I don’t think Microsoft using Chromium is the end of the world, but it is another step down a slippery slope. It’s one more way of bolstering the influence Google currently has on the web.
We need Google to keep pushing the web forward. But it’s critical that we have other voices, with different viewpoints, to maintain some sense of balance. Monocultures don’t benefit anyone.
This essay follows-up nicely on my concerns about Microsoft’s move from EdgeHTML to Chromium in Edge, but goes further to discuss some of the bigger problems of a homogeneous web, especially one under Google’s influence.
