Careful now, you're gonna be called a bootlicker for that lol. Everything Microsoft do is evil according to Lemmings.
You're 100% right though. People on here regurgitate catchphrases and terms that they heard other people in their echo chamber use without understanding what they mean, and because the person who they heard using it also didn't know what they meant, it's just a comedy of incorrect usage of terms.
It's amazing that people still don't understand Microsoft's goals despite them being very open and telling everyone over and over and over - they want to be the defacto solutions on everything, so their stuff needs to run on everything. They will start releasing all of their stuff on linux eventually, because even if only 1% of people use Linux, Microsoft want them using Microsoft services.
Xbox is transitioning to "release on everything", so their upcoming games will all work on proton (apart from COD etc that have anti-cheat, although wouldn't surprise me if they make that linux compatible eventually). Microsoft would rather you subscribe to game pass to play their games on Linux than not subscribe to game pass and not give them any money. It wouldn't surprise me if they eventually released a Linux Xbox app.
