I think it is one thing to write a script and an entirely different thing for a producer to accept it and roll with it.
Not defending her per se’ but just pointing out that if she wrote a script that was intended as an “inside joke” to her producers I think there is a major disconnect here. In the end the producers decide which script to roll with and which ones are “unacceptable” not the writers who I assume are paid to come up with the most outlandish content they can. The writers are not the “conscience” of the show.
I still don’t understand how a less-than-140-character tweet could be construed to be ANYTHING in the category of “script.” I just don’t buy it. She erred - badly it seems.
