> But how many users are legitimately capable of evaluating how privacy preserving a random Cloud AI provider is?

Probably the same number of customers that are legitimately capable of evaluating the privacy of Apple's PCC?

Let's not forget a tiny company called Apple that once proposed Client Side Scanning to "save the kids" by hashing your entire iCloud. Apple loves demanding the moral high ground to promote asinine surveillance mechanisms with no safety guarantees for their users. Senator Wyden is adamant that Apple colludes with the US government to surveil metadata and intercept Push Notifications. Apple's definition of "private" doesn't actually entail privacy at all. Many third-party services are better positioned to protect their users than Apple is.

So why should users defer to Apple's arbitrary definition of privacy? It's obviously bullshit. If you're a traveling journalist, protestor or dissident, you might end up like Jamal Khashoggi for trusting Apple's services to keep you private.
