I find it interesting that people have forgotten Apple's CSAM debacle already and keep saying things like "Apple", "privacy" and "trust" in the same sentence
I mean... they are preventing something actually bad there and doing so in the most private way possible to my knowledge (effectively checking hashes [which don't reveal the actual content of anything] for a match of the hash for something that's known as offending.) Nobody was actually seeing the contents of your stuff. It seems like articles & headlines were out there where people were lead to believe your photos & stuff can be accessed by Apple employees or something when that wasn't actually the case at all. Meanwhile, they have actually delayed this to revise things to further meet the concerns a few people had that had some technical merit.
Meanwhile, I think them doing this (and, importantly, doing it right; keep things as private as possible along the way) helps make it so governments don't try to outright outlaw privacy services, end-to-end encryption, etc. with the common reason of "what about the children", "it's a matter of safety", or something like that. It provide a reasonable way to look for matches of known illegal/dangerous items while allowing the rest of privacy to exist so governing bodies don't "throw the baby out with the bathwater". In an ideal world, full privacy may exist, but then what CSAM is preventing would also not exist... I don't think them doing that is actually an ethical hypocrisy or anything.
If anything, they tried to do something good (giving full details on how it would work)... people still had concerns and told them to refine it further... and they are. Don't really know how they lost our trust or privacy in that process. All while this only concerns their own services & not impacting others. Meanwhile, there's likely numerous other services out there that flat out do what Apple's trying to do (don't allow CSAM-offending content on their services), but isn't telling anyone & might even be doing so in a less secure/private way & people are effectively blindly trusting them instead.
Most importantly, Apple telling us it exists, how it would work, etc. before it even came into play is huge benefit when it comes to being able to trust them. People punishing them for doing that leads companies (and/or governing bodies) to not do so & actually not be trustworthy while still having the public perception of trust (due to being blind to what's actually happening)... nobody wants that. One should seriously reconsider not trusting Apple due to that "debacle"... they did it better than / as good as any company has.
