They're infamous for doing shit like that purely to save face from having to admit they're backpedalling on their BU stance. It's just a coinbase message so it doesn't cost them anything in terms of risk to leave it in there. BU was always just a bargaining tool for them in the first place once UASF was mentioned. Now that they have a way to make it look like they're not actually agreeing to core, even though they actually are, they can finally get rid of it but they're proving their usual level of inertia with previous claims. Most of the other pools that are either covertly or overtly under bitmain's control are still doing the same thing. These morons need to get off their arses and be clear about their message and stop adding conflicting messages to their coinbase. The joke got tired a long time ago.

Segwit2x support over 24 hours is now over 55% making it higher than any activation signal to date and looks set to easily get to the 80% required to start signalling in mid July. Adding the existing BIP141 signalling pools to the total means segwit is a surety unless something happens for them to start backpedalling on their agreement.

This whole approach was really stupid in the first place by the mining agreement and I'm just glad someone stepped up to the plate to make their incompatible bit4 nonsense compatible with existing core nodes and segwit activation.
