A bit before that, it was Amir that brought in the BIP system. Gavin then moved more towards Craig (who he thought was Satoshi), and the group that wanted to fork bitcoin. I actually liked Gavin quite, Satoshi gave him the keys because he wrote the first faucet, and seemed a nice person at the time. But believing Criag was Satoshi was not going to fly. We did incredibly well that he was removed from the project gracefully. 2nd war was also hard fought, but you could see it coming a long way off, similar characters. It was a war around governance, of course, not block size. Unfortunate naming. I suspect there's another war on the horizon in the medium term with influencers that want to fork bitcoin, and those they persuade. This is again not about the feature, it's about governance, and whether there wiil be a chain split, which could be fatal to either side, and devestating for investors.
