I think Linux is about choice some folks opinions notwithstanding. It's an ecosystem where many different devs have chosen to go about the same thing many different ways. You the user then get to pick from amongst those varied and interesting choices.

It however isn't about all or indeed any of those devs being obligated to support any particular choice. You can only buy a place at the table with money or sweat and merely using something isn't contributing and doesn't get you a vote.

Arguably the problem isn't the display server its the fact that general linux usage tends to require a little understanding of what's going on under the hood than is strictly speaking desirable for joe average user especially when something doesn't work. EG needing to understand that your choice of display server is making your zoom calls not work and then having to open that whole can of worms.

The fix is honestly more labor. The trivial way to acquire more labor is with money which is hampered by the fact that so little is paid. If you want more polished stuff pay more.
