Those are terribly run enterprises. I work for a giant multinational that is widely considered to be obsolete tech-wise … I’m on fedora 42 on my work laptop. The team responsible for vetting, security and customising the deployment was ready day one.

Its 3-4 people catering for the ~2-3000 users that use the os internally.

I get the need for stability and repeatability in enterprise. I’m a sysadmin for more than 20 years. That 3 year timeline could maybe move up a bit, even windows deployments are more or less up to date. Why would’t linux be?

Lastly, the more resistance to wayland, the longer it will take for it to reach a level of polish to where even you would aprove of.

When the switch became inevitable (distros defaulting, dropping x11), I installed it, lived with its crappy issues back then, reported said issues and moved on with my day.

Edit: I will say, one thing I still hate about wayland is the sleep behaviour. The 2 x11 systems I still use work well for this, none of my wayland systems want to wake up from sleep nicely.
