I've heard all the arguments. I've had this conversation 10 times now, I already know what all the replies will say. I'll save you all the time, you can downvote me here.

Here's how the conversation goes:

Android User: "With Android I could just turn off Google Cloud"

iOS User: "Apple also only scans as part of iCloud upload process also. So just disable iCloud Photos"

Android User: "But that's a slippery slope! They COULD scan all content of the phone with no effort!"

iOS User: "But they're not currently, and don't plan to. Doing it locally makes it some-what auditable. Also their system as designed would only work for data uploaded to iCloud."

Android User: "So you TRUST Apple to just not add that capability later!? What if a government forces them to?"

iOS User: "So you trust Google not to aswell? If any Government forces Apple to add this on-device, they would certainly require the same of Android"

Android User: "But Apple COULD add it more easily, because this is clearly a backdoor!"

iOS User: "I don't think that word means what you think it means"
