So you manage your own encryption keys for cloud files? Thats pretty much the only way and even then you have to trust Apple because it’s closed source.

They have full control over your device. It’s the same for Whatsapps encryption, where Facebook can still access everything on your decrypted client.

Thing is, most people WOULD CARE if I treat a dog, cat, or any other cute animal the same way as dairy/meat industry does. Why doesn’t the “as long as you keep it to yourself” argument count in this case (might not be for you but for most people)?

It’s about philosophy/ethics and not religion.

It’s more about ethics than morality. You agree that violence is a bad thing? Good. So there is no reason these rules don’t apply to animals, since many of them can feel in a similar way humans do.
