Sorry, but this is really cheap criticism that detracts from the main point. Of course, their private jets (if they have them) should be banned, sure. But this is an invisible blip on the radar compared to the climate impact of the meat industry (or air travel in general).
Such messages only cause people to postpone the need to take real action. And we need to take real action now if we even want a chance to dampen the effects of climate change (let alone reverse it).
