I’m not going to use this myself but I don’t know why everyone’s complaining about it so much. It requires opt-in, it does all the processing locally, and if someone nefarious gets to the point they can read this stuff then they’ll already be able to record your screen, log keystrokes, etc. I expect it won’t be straightforward to view the data as well, it’s not just gonna be a folder full of jpegs.
I’m glad that people are actually trying to make interesting features still. OSs have been so boring years now, it’s good to see people actually trying to introduce standout features even if they are controversial. More of this I say.
