So Microsoft is going to retire EdgeHTML and use Chromium instead for Edge while not really answering the question if the web [is] better off with less engine diversity. This upset people, and Mozilla, especially, is worrying about the future:

Will Microsoft’s decision make it harder for Firefox to prosper? It could. Making Google more powerful is risky on many fronts. […] If one product like Chromium has enough market share, then it becomes easier for web developers and businesses to decide not to worry if their services and sites work with anything other than Chromium. That’s what happened when Microsoft had a monopoly on browsers in the early 2000s before Firefox was released. And it could happen again.

Before you lament the return to a Microsoft-like monopoly, remember what happened to Microsoft’s monopoly. In fact, remember what happened to the lineal descendant of that monopoly just last week. Near-monopolies do not necessarily mean the end of the web.

Yet more in the “EdgeHTML to be replaced by Chromium” story, on which I already shared my opinions. Peter-Paul does a good job of illustrating the differences between the reduction of diversity in/increasing monopolisation of the browser space this time around and last time (when Internet Explorer 6 became the de facto standard way to surf the Web), using it to provide a slightly less-pessimistic outlook (albeit one not without its warnings).
