I get why Microsoft did what they did. I just still wish they would have at least OSS'd EdgeHTML instead of just shoving it in a closet somewhere.
I wish they had thrown in with helping Firefox instead of handing even more web influence over to Google. A percentage of what Microsoft spent on EdgeHTML contributed to the Firefox project—ideally as employee time—would go a long way, along with the counterbalance of putting the Firefox engine and code base front and center of more Windows users.
Maybe they're better at API backwards compatibility now? Not sure; I'm unlikely to try again given previous experience. Which is a shame; I still use Firefox since it was called Phoenix…
If anybody has more recent experience working on their stack, I'd be happy to be correctly though. Preferably with examples of projects that _haven't_ been burned.
