Judging from the threads so far, HN believes Apple is scanning everything using a naive perceptual hash implementation it probably got off of Stack Overflow, with no oversight or sanity checks, and that even a loose match (which will be trivial) means SWAT teams automatically being sent to bust down your front door like the FBI meme, and that it's all just a pretext for CCP style authoritarian surveillance anyway, and we'll all be in dissident reeducation camps by the end of the year.

I suppose it's great if you're looking for entertainment value. For rational, informed discussion of the technology and its political and social ramifications, not so much. It's just the same refrain of "we never bother to actually RTFA but we imagine a boot stomping on a human face forever."
