I see your point. But there is an objective need for a some common ground to applications on. Something with zero install friction and proper sandbox isolation.

Because the alternative isn't "yes, we are providing Linux and MacOS-arm64 binaries", the alternative is "here is your Win32 blob that is broken on wine because screw you that's why" or "here is a .jar with a horrible awt fronts that is also broken unless you run it under an ancient JRT" - and that's on user's side, on developer's side it's even worse. I feel that web becoming an application platform was net negative for the web, but positive for every other platform (and users and developers as well). Yes, it makes web crappy, but we need some crappy platform where all the crap goes - and at least the browser contains the crap well.
