I think the adoption everyone is looking for on desktop is deceptive. The type of people that run Linux on desktop are averse to Telemetry and so desktop Linux will report much smaller numbers anyway. Consequently, everyone is hoping for Linux to become the standard in the professional space and there, it's back to application support and the big one, compatibility. It's all good if everyone in an office is using Linux, but they need to interact with the outside world, and if the outside world can't read what they send, then it's not even worth considering switching.
