The problem with UWP is that nobody liked or wanted it, so obviously it died. Developers got locked into a walled garden, Xbox users saw no benefit (until recently with emulators, but I digress), Windows phone users practically didn’t exist to build apps for, and PC gamers got the real short end of the stick with everything becoming a buggy, locked-down, performance-hampering, feature-lacking mess.

Outside of letting Microsoft half-ass port some Xbox titles to PC, it was pretty much useless.

Sounds like good moderation to me. Terrible title that implies an opinion is wrong and that OP was never interested in discussion at all. Talking at people isn’t talking to people.
