I think he's just saying they will use data to determine which type of show gets funded, but will not to use it in ways that affect the internal logic of the show. So they may fund a show whose main character often goes to a coffee shop because viewers appear to enjoy that, but they won't change an existing show to make its main character go to a coffee shop because it might not make sense for the character to do that in the context of the given show. And since those involved with the data and funding process will naturally have less understanding of the show's characters than the writers, they won't attempt these changes even when they appear to make sense for a show. Of course, writers could adapt and force things to happen in a show that wouldn't otherwise, but I don't think funding certain types of shows is equivalent to changing existing shows to fit a mold.
