I can pick up pretty much any PC and install whatever OS I want on it.
There is a plethora of thriving communities and unfathomable amount of diversity and options.
Phone hardware are in most cases locked down, and even if they are not the bespoke hardware with terrible support is pretty much unusable. There are software alternatives but they are severely lacking and often lock you out of core features that even the most modest smartphone user expect to function. And that society expects you to be able to do.
Comparatively a PC is nirvana, I know apple is trying their darn best to change that but it is in a pretty good state.
The mindshare and actual usage is also several orders of magnitudes better.
