So google is "censoring" these two pubs by saying we won't pay you anymore by allowing our ad networks to be on your site because we don't like what people say there. Up thread someone says google is less than half internet advertising. So is it still censorship? If 3M doesn't like something in the WSJ, is it censorship if they stop advertising there? I get the point, that someone exerted force on them but is stopping giving money censorship?
