I don't think my framing is cynical (or wrong). Facebook has a clear incentive to reduce CSAM reports and end to end encryption will help by preventing automated systems, which do most of the detection, from detecting CSAM in messages. I don't think its Facebook's only motive for implementing end to end encryption, but I doubt they haven't considered it. It's good to give users the options to report such materials. As I mentioned though, the majority of CSAM detection is done by automated systems. I might guess that if two pedophiles are trading CSAM via Facebook messenger they will be both be unlikely to report the other.
