You asked for why bip110 is a threat. Odell is saying it's a risk of a very late chain reorg. That happening days/weeks/months after activation is a pretty big problem.

It’s a threat to the donor/funding mechanism of Core/Odells companies.

Problem to who? Those who want Bitcoin as money only - will have achieved consensus… fairly in this case. It would be a massive problem to ALL THE DONORS OF CORE LOL 😂

For anyone who gets a transaction mined and then gets it reorged. That's every transaction on the reorged blocks not just the spam. That is massively disruptive and could significantly undermine Bitcoin. I'm not sure if that's as disruptive as csam on chain but it's a reasonable question to think about.

There is nothing more despicable than illicit spam on chain - @Adam Back even developed ways to eliminate it for hash cash in 1998… yet after meeting with Epstein he changed his mind… If the miners want to participate in that - they will lose everything - as they should because bitcoin would not be sound money
