You are comparing Apples to oranges. While it may be true that Linux may have more software available, in my experience macOS has a shit ton of productivity software as well, and many times, due to being for-profit, of higher quality. That’s exactly why I’ve been thinking about giving my own try to making a launcher like Raycast for Linux.
If I were to end up doing it (too many things I would like to do, too little time), I’d do it foss. At most I’d paywall features that have an ongoing cost (like hosting or server costs), though I am a bigger fan of keeping things local. That way its simpler and also easier to trust.
Personally, I think that paying for software isn’t a bad thing as long as the price is right and the licensing reasonable (I really hate unnecessary subscriptions). Devs (specially if working on complex stuff) got to eat too, and sometimes donations aren’t enough.
