I don't know much about these type of laws. I was on Carnival's Holiday in 2001, and they were videotaping an episode of "Shipmates". I was in one of the scenes they were doing, and they asked me to sign some type of waiver. That was from the production company though if I recall. Thank goodness I was edited out of the episode.
Again, my only problem would be the use for commercial gain and distribution without my express permission.
It is actually a good thing that people are reading the fine print in the contracts. Not much one can complain about once they agree to it.
