You seem to have misunderstood "good" to mean "everyone involved in the project will make equivalent to what they could have made working the same number of hours in Silicon Valley". When really all I meant was that the founder, and maybe sometimes a small group adjacent, can afford to spend all or at least part of their time maintaining and steering the project. If that's your argument, then you and I are in agreement.
Another commenter in this thread said it best - Open Source is a community. People participate in it because they enjoy doing so, not to get rich. If I can do something I enjoy, on my own schedule, entirely freed from corporate interests, and get rent money for it, I would certainly call that "good".
