The author is a tech lawyer. I think the article is there to start discussion. I agree with him that if private venues allow people to record like this they should offer, at the very least, an opt out. "Purple lanyard" seems like a good way. It's also a pretty easy spot in post production where you can either blur or cut as appropriate.
It's all about balance. Private venues want their customers to have the best experience they can so they will want to come back. The purple lanyard solution MIGHT work, depending on the ratio of people wearing them and the number of people filming. Or it might be that lots of people want to film and the one guy with the purple lanyard keeps getting in the shot and ruining it. Or it might be too many people want to film and end up ignoring it. But in the best case, it allows youtubers to make their videos while not requiring those who don't want to be in them to stay home, as non-customers.
I occasionally see people saying “well, if you don’t want to be in photos published online, don’t be in public spaces”.
This is nonsense, for a number of reasons. Clearly, one should be able to exist in society, including going outside one’s own home, without needing to accept this kind of thing.
In any case, here, the issue is somewhat different, since it is a private site, where people engage in private activity (a hobby).
