The government is the curator of the “naughty image” database……EXACTLY!
This has ZERO relation to what corrupt governments or those with dubious human-rights/censorship tendencies (such as China) may WANT to do. This is something APPLE (who as far as I am aware, for all it's fault are trying to do something genuinely GOOD here with good intentions) are instigating for their own systems. They wouldn't even unlock phones for the FBI for peat sake so they're not going to just open up their systems for China (or other nefarious governments) to do 'evil' things. People in the USA in particular it seems appear in a perpetual state of fear and mistrust. It's what help Trump rise to power and continue to hold sway with millions of delusional followers.
this most certainly will become corrupt and politicized
