Yes I was about to say the same thing. Hash collisions are an extra concern about what apple is doing, but even if they were as collision free as cryptographic hashes, that would not make the invasion of privacy OK. The technical discussion is something that apple can easily parry and is the wrong framing of this debate.

I'm so glad you said this.

As someone not in the tech field, it is incredibly concerning that half the people here on Hacker News, people who help build this kind of technology, do not seem to be concerned with what Apple is doing.
