Furthermore placing our trust in the Core development team is a far more dangerous form of centralization then compared to anything else that is within the Bitcoin XT client.
Distrusting XT or BIP 101 =/= trusting the Core development team. That's another blatant mischaracterization that keeps being throw around. Please keep the discussion honest.
I think what VeritasSapere is getting at is that Bitcoin's greatest point of centralization is presently Development:

Solex made in interesting observation
here: Node count has actually
increased with the release of Bitcoin-XT. If we had even more competing clients to choose from, perhaps we would see a further increase in node count as people ran nodes to express the vote for the direction the protocol should take. In my opinion this would be a very big positive because it could simultaneously increase node count AND decrease development centralization around Core.
