I looked it up.

He went to a non-official startrek convention recently, during all these strikes. All the other star trek actors weren't allowed to/avoided talking about star trek directly because it is owned by a company they are striking against (with the exception of the animated shows I guess?). He apparently talked freely about startrek without any concern as though he doesn't care about the strike.

I was wondering too, because I was wondering how a well known actor "scabs" exactly, but this makes sense, he is still promoting the show, disregarding the strike rules and working class actors.
