I would assume that many posters doubt that Williams gives her any simulator work. Since Wolff has no talent and is only allowed on track for marketing reasons their would be absolutely no reason for Williams to let Wolff into the simulator.
People are arguing that they shouldn't let her into the simulator, not that they don't. I've no idea how much work she does in the simulator or how useful her feedback is compared, for exanple, to what they get from the race drivers. Nobody's arguing that she's entirely useless in that regard, only that there are plenty of other drivers who haven't had the chance to show what they could do if given the role of development driver, who would have been a better bet.
