Just commenting because this is a really good point and I'd love to know whether there's an answer besides "the other folks mentioned are loved more by the internet", since I really don't know about the specifics here.

I do understand the rationale behind "there are non-writers who work on the show and they still need their jobs", though. While it would be nice if this strike turned into a general strike in the entertainment industry, I don't even know how many of those other folks are unionized.
