The guy tried to sink the pound. His ngos funds people helping migrants get to the US Mexican border to illegally cross. Pretty sure he's supporting Thunberg. He certainly does the cancer that is Media Matters. He throws alot of money into various projects. Some people appreciate it, some don't. Not that he's responsible for all the world's ills, but I still think he can be criticised.
