Yeah, understood.
I still think that maintaining an active community in which to find players requires some support and constant input of energy.
Clearly existing 1E groups prove that my claim is not a fundamental truth. But if you moved to a new city and started looking for a new group, I bet your brother would find a Pathfinder group a lot more quickly than you would find a 1E group and would have more variety of groups to choose from. (at least 19 times out of 20)
If you have a fixed group and none of that matters, then cool. But fi you have this solid group of like-minded gamers, then power-creep shouldn't be a problem. Everyone agrees not to use crap. Again, I readily admit that the D20 glut included a ton of bad, overpowered crap. (include plenty by WotC) So I hear you. But it is easy to avoid power creep in a group that is averse to power creep. Don't use the power creep stuff.
So I'm REALLY not trying to be the least bit critical of what works for you. It makes sense. I just don't see how them publishing things you don't have to buy is something you should, be opposed to. Publishing more stuff helps you indirectly through supporting the community. Not publishing obviously doesn't hurt you, but it denies others what they want for no gain. So why take the position?
