Because bitcoin is what he says it is, any other proposals for scaling bitcoin cannot be discussed under his domain and should be considered altcoins, because that's how a decentralized technology works.
Wrong. They aren't proposals, they are programmed altcoins. A proposal for example is SegWit while XT/BU/Classic are not proposals. You are being influenced by the very people that are trying to harm Bitcoin.
Gavin Andresen, Mike Hearn and Jeff Garzik are developing bitcoin pretty much since the beginning, why would they want to harm bitcoin? Where did you get that idea from?
