So already, this person wearing these glasses are already agree with that Meta can monitor them. They also probably trust Meta when they say "When the glasses are off, nothing is recording", for better or worse. So with that perspective in mind, it's not far fetched to assume these same people will willingly be naked into front of these recording devices they believe to be off.

Of course, anyone who opened a newspaper in the last 10 years or so would know better, but I can definitively see some people not giving a fuck about it.
