After seeing what Theil did it made me look at the world slightly differently in a more open way that money and those with a lot of it could be behind so many things in our society from politics to whatever. Everything can be bought/manipulated/etc based on the desires of the richest people whether they are open about it or not. Thus, I don't believe much of what I see and read especially in politics.
FWIW, I'd argue that Theil's actions were a rare example of that sort of thing happening semi-openly. It's probably always happening behind the scenes to all other publications by all people of that class. The rest of them just have better cut-outs and relationships already established to quietly kill anything they don't like.
