I mean, the obvious point here is that none of these people are selling linux (or wayland or whatever). You could argue some of these projects over promise in terms of features and so forth, but again, it's not like people are paying for it.

You can certainly be unhappy with a piece of software regardless of if you paid for it, and there's an argument to be made that linux users benefit from it becoming more popular, but we're still mostly talking about volunteers creating software for themselves and then choosing to share it with others.
