Linux people are very resistant to this, but the future is going to be sandboxed iOS style apps. Not because OS vendors want to control what apps do, but because users do. If the FOSS community continues to ignore proper security sandboxing and distribution of end user applications, then it will just end up entirely centralised in one of the big tech companies, as it already is on iOS and macOS by Apple.
Linux people are NOT resistant to this. Atomic desktops are picking up momentum and people are screaming for it. Snaps, flatpaks, appimages, etc. are all moving in that direction.
As for plain development, sadly, the OS developers are simply ignoring the people asking. See:
