I can appreciate the fact that theymos is actually standing up for what makes sense in terms of the bitcoin protocol.
XT and BIP101 would be a very unfortunate thing to see take place and I pray that this doesn't become the case.
Most of these companies only care about a quick buck.
I think its a fair statement though. If they somehow can affect the growth of bitcoin community, then it must be fair to simply have restrictions the community wont find coinbase helpful. What's good for them is where they better stick, after all they started with bitcoin.
