Bitcoin is and has been used to pay for much CSAM and much worse CSA but we all still use it as money. Unfortunately reality, but it’s outside of my dichotomy of control.
If someone adds CSAM to an OP_RETURN that gets hashed that event is completely out of everyone’s control (minus the person who submitted the tx) and has nothing to do with bitcoin or me. CSAM can be hashed on-chain without an expanded OP_RETURN as well in many different ways and some say it has already happened, though I haven’t seen proof either way.
I will continue to run my node and use bitcoin as I see fit and remain stoic in the face of propaganda and attacks.
