The whole point of them using chromium shows how little they care.
The old edge wasn't used much no but that wasn't due to its engine. Most people don't even know what a browser engine is.
They just didn't want to bother making a browser. But they want to benefit from the marketing advantages of having a browser so now they just lift along with chrome.
I think they do care, but they care about relevance, not browser monoculture. Doesn't matter how good Trident was, no one was ever going to use it. Even Firefox is barely hanging on, and the only reason Safari is still somewhat relevant is because it's the only choice on iOS.
And my relevance I mean their bread and butter, enterprise, not consumers. Edge is what lets MS give enterprise IT departments maximum control without the grumbling of "we'd rather have Chrome" from the end users.
Well that's the thing. I don't think anybody didn't use Edge because it was a different engine. The majority of users have no idea that edge is just chrome now.
It's just when they moved to chromium they also stepped up the marketing around it and all the lock-in in Windows and that's really what got people to use it. Basically the same thing they did to make IE a monopoly.
They also really heavily pushed companies to start using it. Every time we had a call with a MS consultant and we shared a screen they had to bitch about us not using edge, as if they were on commission or something. Eventually they manipulated our leadership into mandating edge to all employees. It's totally locked down now too, it's terrible for the users.
But my point is, they could have done this with the trident version of edge too. I've never heard anyone complain about compatibility. Whenever people didn't want to use edge it was because of a (totally justified) distrust of Microsoft. We should never give control over the internet to them again after what they did with IE (making it a monopoly through illegal means and then leaving it to wither away full of security holes). But unfortunately at work they have got them to remove all other browsers :(
