I see your point here - this is a slippery slope for Apple. However I don’t see how anyone could achieve both purposes - no fingerprint reporting and prevention of CSAM storage on Apple servers.

Also, a practical thing to do is to just not store your photos on iCloud but use something else for sync and backup - there might be a startup opportunity here if enough people care.
