What that tells me is that you are fine with Big Brother.
It tells me YOU were fine with Big Brother considering ALL OF YOUR DATA is decrypt-able server-side since 2014. It wasn't until social media threw a fit is when you started making a fuss.
This is different than what Apple has done up until this point. This is your devices self reporting to law enforcement.
No. You turn off iCloud and it doesn't self report. You turn on iCloud and it self reports.
This is no different than Apple scanning all photos serverside. You turn off iCloud, server doesn't report. You turn on iCloud, server reports.
The other things you mention require law enforcement to suspect, independently of your phone, that you’re guilty of something and to obtain a warrant.
So is this feature. The only way for law enforcement is able to inspect is for at least 30 photos to be matching against a database of illegal images.
And law enforcement is only able to inspect the matched images and is only able to see visual derivatives of those images.
This is substantially more private than law enforcement being able to look through your ENTIRE iCloud backup and iCloud photo library.
You might say:
"But someone might attack you by feeding you legal porn images that collide with child porn"
No different than someone dropping a gun into your bag before you hit TSA checkpoint or a million other ways of framing someone. Law enforcement will be alerted, they will review, and they will let you go.
Further, there is spyware that can pwn your phone just by viewing a text message.
No there isn't. But if there's something that can take complete control of your phone, there are more effective ways of framing someone for doing something they didn't do.
What if your spouse or significant other is vindictive and wants to leave you and get some revenge? If they know your passcode if you don’t have one what’s stopping them from uploading some images knowing Johnny Law will come knocking assuming your a pedo?
What's to prevent your SO from grabbing your phone now, sending pedo images to the local police department's email pretending to be you?
If you can’t see the forest through the trees that’s on you.
You didn't make any good arguments so I disagree.
