So in your view it's perfectly ok to run an internet service where you don't check for CSAM? You're entitled to that view I suppose but it's a minority view and allowing CSAM on your platform is illegal in most places (including the US where there's a carve out for that sort of stuff in the law that protects Google, Facebook et al) and in all of those jurisdictions the public is not going to be able to see the CSAM or be able to examine the substance of the allegations either before or during trial.

Every social network or file sharing site that I've been aware of has a Trust and Safety department for just this reason even X. The executives don't want to go to jail.
