The vague "this is a serious concern because my government is shit" requires a person to ignore a lot in favour of a little.
I think you missed OP point, the grandparent found a bad excuse for Apple, that Google and Facebook do the same so nothing is wrong, but the OP responded correctly that this is false, those companies don't install file scanners on your device so the excuse is bullshit.
They don’t install file scanners on iOS because they cannot. They are happy with scanning my contacts and doing who knows what with my photos if I let them, though.
Nobody says that Google or Facebook are good/saints, but there is a difference, my phone did not had Facebook or WhatApp installed, so journalists or activists can just don't install this crap.
> Then you should already be gravely concerned
I am concerned. I explicitly wrote "...not only plausible, but is of real concern."Reverse this for a moment: would it be acceptable that a Chinese tech behemoth decides US law does not apply to their American operation, because they are convinced that western democratic values are dangerous?
This is also a real concern. If you think that rule of law is a good thing, then companies must comply with local laws. The alternative is not a humanist utopia; it is the rule of unaccountable corporations.
In this case there is no law to force Apple to scan on device, they can scan iCloud only if the law forces them to do that, or scan only iCloud images that are public or shared if the law forces to do only that.
Before 1989 listen to a specific radio station was illegal , but the good part was that the radio device could not snitch on you , if someone would have invented snitching radio then I am 100% only those radio devices would be legal to be sold in my country at that time. So if you create a snitching device then you invite the bad governments to add the laws after to profit from that and make their lives easier.
