As node runners we intend to preserve Bitcoin's primary usecase (money, not JPGs, not "data").
The current spam is obfuscated and fragmented (and Core is responsible for much of it by REFUSING to fix Inscriptions exploit bug).
100k OP_RETURN will allow for high fidelity CSAM images in an inmutable blockchain. We did not sign up for that crap, so forgive me if we are playing defense here by trying to preserve Bitcoin.
