As a non-lawyer forum commentator I can say with absolute correctness that it will (or will not) maybe apply.

More seriously: I would guess no, as the GDPR is concerned with data collection and compromise, but I can’t imagine they store all the video they forward.

Of course I wouldn’t be surprised if someone sues them in the US (but given that the US sees companies as people for rights, but not punishment I imagine that they’ll be fine).
