Yes and no. While the higher end writers are very well off with what they have now, there are legions of lower end writers that write for shows that don't quite make the big bucks on TV and considering that a lot of the money these days are made from DVD sales and other non-TV sources it is fair the same creative rights translate accordingly seeing that the writers did get ripped off almost 20 years ago regarding DVD/VHS sales.
As with reality shows, do you really honest to god think that stuff is unscripted? Sure most of the dialogue outside of narrators are indeed unscripted, but the scenarios, entire premise of the show had to be written by someone. Someone had to conceive the stupid challenges, events, the overall progression. Otherwise you end up with 24 people starving to death on an island or whatever hell hole they can find.
If I also understand it right, I don't think they are breaking their contracts. Their deal with the studios dates back to the 80's and it is only now that it has expired. Do you really think that they are collectively that stupid to open themselves up like that to lawsuits? As with the actors going on the picket lines, most likely they have no work to go to anyway, contract or no contract. It also doesn't hurt them since one, they are already effectively out of the job, two, by applying additional pressure they can resolve the situation sooner, not later, three, they can expect quid pro quo in the future.
Family guy with out Seth Macfarlane. Dude, he is Family Guy. That is going to create one whole season of pure suck. Oh well, no matter, my plate is full enough as it is with study and general ethanol consumption.
