I see. I was responding to you, yes. And in this case I was more curious about your opinion - based on your previous knowledge - on the viability of Apple’s technology here, rather than the specific details of your work.

In my (uninformed) opinion - this looks like more of a bad faith move on Apples part that will maybe catch some bad actors but will be a net harmful result for apple’s users and society, as expressed in the Twitter thread.

Others who responded here though also seem to think it’ll be a viable technique.
