Coinbase has been delaying segwit for ages now. I have seen Brian Armstrong support BCash also known as Bitcoin Cash, and I have seen him saying how "It's likely Ethereum takes over Bitcoin soon", I have seen him talk a lot of shit basically.

Now, I think I may give him the benefit of the doubt on delaying segwit until at least May, because Bitcoin Core 0.16 does not come out until May and this will be the version that supports bech32, so they may be waiting until then, im myself waiting until then to use segwit at all.
