Informed? You mean manipulated, right? Watching open television makes me physically sick because of the constant agenda pushing. I can't watch 5 minutes of news without some person imposing their moral judgements on me and telling me what's right and wrong. It's made even worse by all the advertising, the open networks get the bulk of it.
If banning advertisers kills these networks, we'd be doing humanity a favor. Facebook's election manipulation and clickbait news articles have got nothing on these folks.
