any public utility is like the phone company, they are legal monopolies, you only have one water pipe, telephone wire and electric wire coming to your house so the government grants those providers monopolies and as a result they have to be subject to government regulation and oversight.

I think that you are on to one possible solution of the problem but that the current law does not currently apply to them for various reasons. Some legislation is needed for that solution to occur. Congress could declare the alphabet to be public accommodations. They would also have to make political affiliation a protected class to keep people from discriminating on that basis and as we see from various incidents of people being thrown out of restaurants, which are public accommodations forbidden from discrimination in who they serve, political affiliation is not a protected class except for employment in some cases. In who you serve you may discriminate on the basis of political affiliation under federal law.

If free speech laws apply then a corporation should be free to decide what is said on their website. So I think a better solution to this problem is to let these giant CIA backed quasi monopolies ban who they want and be totally biased and evil and for all good people to use sites that don't do those things like @steemit and to let Facebook and twitter pass into internet oblivion like Myspace when the next thing comes out which will hopefully be steemit.com.
