Likely germany, we have very strict recording laws. It’s actually stricter on audio recording, due to Germany’s history: you’re not allowed to record people without their consent if they could expect privacy, which includes outside when for example 2 persons are talking to each others privately. That makes the meta glasses pretty much illegal to use in most situations, though I don’t believe that specific situation has been tested in court.

Note how it’s about recording, not sharing.

(It’s way more nuanced and complicated in practice of course)
