Censorship is stupid easy to prove.

It's a known fact that Facebook has been reducing the reach of posts from news outlets that don't pay. If you run a small town newspaper and have 1000 facebook followers your newest post may only reach 200 of those followers unless you pay to promote it.

I get about 10% to 15% reach on Facebook to people who follow my site. For $5 I can get about 25% for around $40 bucks I can reach about half of the people who clicked saying they wanted to see my content.

Google skews results as well plus they use a nifty trick. Search google for say Home Depot. The first listing will be a listing for Home Depot that is an ad and Home Depot gets charged if you click it. Scroll below it and there will be the google result which they don't get paid for.

But I wouldn't expect any regulation coming soon. This Congress and president aren't upping regulations.
