As you explained, if Antpool were trying to maximize profits (short term) then they would mine on their own block during a chainsplit.
What are you opinions on the following reasons why Antpool would abandon their own block during a fork?
Antpool does not want to be "liable" for a 2+ block chainsplit that could appear as an attempt to reorg blocks (its a way to guard reputation as an "honest" pool)
Antpool is using the Tit for Tat Strategy (its a long-term strategy of mutual cooperation)
Do you have a theory why a pool would mine on the competing fork?
Suppose Antpool has demonstrated a pattern of mining on the competing fork (as opposed to mining on their own block during a fork).
