Streaming at in person chess tournaments

I see where Alexandra Botez and Anna Cramling are live casting their tournament games at Rejkjavik.  While I believe this can only be good for chess, can the opponent refuse to be filmed?  Mostly because the chat can be rather crude toward the streamers opponent (making disparaging remarks about looks, etc.) and the opponents can't respond.  Also, are the streamers being paid through Twitch?  If so, do the opponents get a cut, because they are in effect the co-star of the production.  Personally, I wouldn't care, but I know some people would.

Don't record Sonny Corleone.

But can they refuse to be recorded?

At invitational events there is probably something in the invite that by accepting the invitation you are giving the organizers rights to film you and the event.  It's been a while since I've played in an in person open event and since this is a recent phenomenon, maybe there is a clause that by entering, you are giving consent.  Isn't it the individual streamer not chess.com who is responsible for the recording, at least in these 2 cases?

I don't know why either, but some people don't like to be filmed by people they don't know, especially being the sole focus for hours.

I'd have fun with it and make goofy faces at the camera or something.

I get so wrapped up in the game when I play in 40/2 tournaments, I'd forget the camera is there.

 Hopefully, this is all worked out by the organizers and players can request before the tournament starts not to be paired with a streamer unless it's a forced pairing.
