how do you expect them to fix Zoom? Acquire the company and take it behind the shed?
I mean, you could - for example - implement the interface these apps expect to exist and use with your amazing new compositor™.
This is precisely why companies just say “fuck Linux users” - instead of supporting a single operating system where everything kinda “just works” across versions for decades you have to checks notes support 20 different compositors across 2 vastly different display servers and dozens of various desktop environments and such… All for an OS that’s used by maybe 3% of your users if you’re lucky.
