Community division in Bitcoin is a feature, not a bug. I think Giacomo lost the plot at some point. I used to like his takes a lot, but his main objection to BIP110 is that if a contentious soft fork activates due to the game’s theoretical asymmetry, it could set a precedent where other BIPs ranging from beneficial to largely irrelevant (such as Drivechains) might also be activated by coercing miners.
