Meta is going to get into trouble for this because it looks like they are saying everything that is in the public domain is ours to do with as we please. The problem is not everything is public domain though. You walk into a shop that sells goods to the public but it is still a private business though. Public transport all have conditions of using recordable devices on or in their premises or transport.
When you walk into shop, a business, a public building, you are still agreeing to the terms and conditions of entering the building. Meta's excuse will be that it is the responsibility of the glasses wearer to remove the glasses in places where it specifies that recordings inside the building are not allowed.
I have no doubt there have been people wearing these ray bans where they have been in situations that would cause a breach of the law. For example, catching children and/or adults in the nude, catching them dressing and undressing, catching acts of a sexual nature, whilst all perfectly legal whilst in the privacy of ones own dwelling but as soon as such images gets transmitted to Meta, it immediately becomes illegal due to the various laws on what can and cannot be recorded and electronically transmitted to storage devices.
You have a mother or father wearing the glasses, they are in a such a rush that they forget to take them off whilst getting their young children ready for school (washing them and dressing them meaning their children at some point will appear nude). Another scenario is someone wearing them and forgets to take them off whilst going into the locker room where their are people dressing and undressing, naked bodies on view. These glasses will be recording and sending images to Meta's services. Now here is the problem, as soon as nude images of children are sent to Meta's servers, both the wearer off the glasses and Meta have broken the law. If images of people getting dressed and undressed in a locker room, again the glasses wearer and Meta have broken the law.
Therefore, as I said, these glasses could get the wearers and Meta into heaps of trouble. I have no doubt there will be privacy advocacy groups making claims against Meta.
