That there is a desktop OS where everything is open reminds people that are alternatives to walled gardens.

That is a far cry from "useful pressure".

There are more pre-installed Linux desktop/laptop/handheld devices being sold today than ever.

For end users, WSL and Crossover do allow for more freedom than if these things didn't exist.

I mean, there's an argument to be made that Android / ChromeOS / Fuchsia wouldn't exist without Linux either (i.e. not exist as they are or in some similar open source variation). They don't stand quite as independently as you suggest here.

The comment I replied to was specifically about Linux on the desktop, not Linux in general. I didn't claim Android etc wouldn't exist without Linux. Linux on the desktop is just irrelevant to commercial desktop OSes. Microsoft, Apple, and Google don't care one iota about the latest updates to GNOME or KDE.

Third parties don't care about the Linux desktop either. If Linux is even considered it's a distant third place. If Electron dropped Linux support tomorrow a good number of applications would drop Linux support the next day.

Even the likes of Valve supporting Linux is more of a hedge against Microsoft than anything compelling about desktop environments on Linux.

Go count how many Windows desktop features were widely used on Linux first.
