firstly now your just finger new topics found on twitter rather then discussing the reality of segwit adoption

secondly no one said antpool is perfect. they do empty blocks and other things too but not as much as a certain group of propagandists think

thirdly. ya maybe some of the "antpool" tagged facilities have yet to desire to adopt segwit.

fourthly , this indirectly points out something. pools can and do decide whatever transactions they like to be included or excluded
for instance BTCC would add any transaction that came from their exchange at 0 fee but made others pay high fee's to be considered into BTCC's blocks...
for instance there are some pools that refuse to add transactions where only a couple $ worth of btc is being moved

but i say this because nothing stops pools from doing this. by this you will also find that no pool is going to be forced, made to, or coerced into  including a LN close channel session onchain. yep its just a tx. and pools could ignore it if they want. so dont expect LN to come with guarantee's of ontime close sessions or expect segwit to get high adoption.

and you will find that when it comes to adopting new tech if you dont support it you dont have to just keep mouth shut and do as core say.
