Guess Antpool would never be able to grasp the philosophical notion of pool neutrality.
If the miners supported BIP148 and they were actually principled enough, they would switch to a pool which supports BIP148 or allows them the option of mining on that chain.
Individual miners will act based on their own economic incentives - pools will act based on their broader/long-term economic incentive.
If pools believe that they have no broader economic incentive to support a specific solution, that's the only situation in which they'll be neutral. This applies to other pools, including SegWit supporting pools, not just AntPool.
As far as my understanding goes activating Segwit/BIP148 would be one of the best possible solution for the scaling issue. Jihan Wu is openely against Segwit, he owns the biggest mining pool, but as far as miners are concerned their long-term economic incentive lies in activating Segwit, that's the big picture, those miners who can't see this are just cashing on the current situation without giving a second thought.
This comment was posted by Reddit user, Lejitz in response to, everyone should remove hashpower from Antpool:
Surely you realize that much of their hashpower is their own. And also that much of the hashpower of the BU pools is actually controlled by Jihan Wu, who controls Bitmain.
I know you are in the loop on these things. Not only can we not remove the hashpower of this guy, but he has a practical monopoly on ASIC manufacturing and is using his influence from that position to also stop other miners from implementing SegWit. (i.e., "I will not sell you hardware if you support SegWit.")
If Segwit gets activated this guy can't do anything, BIP148 gets enough support, miners would switch. Even if all these alternatives fail, there is BIP149 which I believe core developers are in favour of would be deployed.
Jihan Wu is just halting the inevitable.
