Pretty sure someone could experience serious ramifications if they persisted recording you after being asked to stop. They might even be met by police at the destination and banned for life if they refused the commands from flight attendants after their inevitable involvement.

Flight attendants do seem to have a lot of discretion when it comes to instructing passengers and I know that failing to follow safety related instructions can lead to bans or police involvement.

I'm not sure if they'd be able to extend that to someone recording me although it likely varies by country. I think British law considers continued recording a form of harassment where the same protections don't exist in America.

If I was really really bothered by it for some reason I might raise it once. The cabin crew has the safety of the flight and other responsibilities to be concerned with.
