Well, VSCode is a bad example. It's open source so if Microsoft decides to ditch it, it can be community maintained until people move to something else. Or another foundation can take over or another company can fork it. Come on, VSCode is a "lightweight" IDE ("lightweight" in terms of features, not in terms of resource demands) and it's one of the better ones.

I remember its first version and my first impression was "WTF". Nowadays it's pretty usable. IE of its era really wasn't. You can switch to anything else if you don't want to use VSCode. IE ... you either couldn't (on a company-issued computer) or you didn't know how (at home). Nadella's Microsoft is a far cry from Ballmer's.
