Apple's announcement that beginning in iOS 15 they'll scan photos on your device before you can upload them to their host service (iCloud), hash them, and report them to the government police if the hash matches an existing database of hashes, means that Apple cannot be trusted anymore. It's not a surprise. In fact it shouldn't be a surprise to anyone worth it's salt. But it was written on the wall already. Very scary surveillance world we are getting in, guys.
Of course, you can simply stop using iCloud if you did. But the repercussions of those principles are so wide that it questions whether owning such a device makes sense anymore.
