When the writers all quit and people assumed it was Doherty, she released a statement saying she wasn't the problem they were speaking about and I believe her. Jeannie Garth and Tori Spelling are the ones who came up with this idea and who are in charge of it. They're the reason we're getting a mockumentary (like Tori's soNOTORIOUS series) and not a proper reboot. Remember, Doherty didn't even join until much later on in the creative process. The writers quitting HAD to be from Garth and Spelling because they're the ones with the main power to do something like that.
