I am all about kill your heroes etc, so I don't follow her and only hear about her every few months, and while I am always positively surprised, she wouldn't be the first to take a nose dive at a moment's notice. At the same time, I don't think she's actually trying to sell out, her shit is extremely unsellable ever since she dropped the lib "school strike" and went in with more hardcore activism. I think she might be genuine, and I say that as somebody who thought she was just a preppy kid back during her strike years (she comes from a well-off family etc).
