Don't get me wrong, I obviously want everyone to have access to what's practically "running code" of the collective system, and do want those protections... I just think that in a p2p system it gets a bit thornier.

But as I said, I think GPL does better in P2P than in C2S (though is not immune to people trying to centralize nodes either for sure, and one can look to bitcoin to see some centralization in a p2p system happening, practically seeking... that's more of a problem with how that protocol works/scales than someone doing something of trying to hide code behind their network though IMO)
