I'm honestly not sure what you're refuting here. Are you saying the hash DB can't be updated or that already uploaded photos won't be compared to hash updates?

  The hashdb is part of the operating system and only gets updated with OS updates. It can be updated-- at some cost. But if it is very frequently updated then the protection against receiving a targeted list is lost. To state it another way: Users ask "Why won't the government order apple just gives me a list of the hash of every political image on the internet in order to expose my files?" and the answer is that the database is part of the OS, common to everyone, updated infrequently, so it can't be used in targeted attacks. That protection is lost if the database is frequently updated. It's also true that already uploaded photos won't be rescanned, but that wasn't the point I was trying to make.
