I totally disagree it was unnecessary: I am convinced that it is exactly that behavior to explain a lot of the current situation of "anti-Core sentiment", way more than the technical point itself, which I consider, like the video author, a nothingburger. The video itself is ending with a (imo correct) analysis on possible social consequences, beyond technical ones. Thus I consider it unfair to blame me of "turning a technical debate social" if I comment this point.

My answer to your question, before the fork proposal, would have been definitely A: when the CSAM FUD emerged, a few months ago, the conflict was already since months at maximum possible escalation levels, with reciprocal bad faith assumption, very strong public accusations, github moderation abuses, lobbying to investors to defund Luke's mining project, bans from physical meetups, etc.

After the fork proposal, maybe B could be true, but not sure. One one hand, the fork is intended to avoid "sanctioned/contiguous CSAM encoding onchain" (which I don't think makes any sense, without a hard fork to also remove the not sanctioned/contiguous one already present, which I would consider overkill anyway with respect to the legal risk): Luke's implicit accusation of moral complicity by developers doesn't play a central role in it. On the other hand, it seems like many fork proponents think that this aura of moral complicity may be in itself a key reason for the fork success, so maybe it's B.
