My take on this is that corporations have a right to ban individuals on their respective platforms for many reasons.  While this isn't necessarily a freedom of speech issue, it is definitely a censorship issue.  Freedom of speech would imply that the government is making it illegal for people to express themselves in a variety of different ways.  However, here we have an issue where the government is supposedly not involved.   For the record, I don't agree with a lot of what Alex Jones says, but I do believe he should not be censored because a certain group of executives have decided that he is a threat to their platform.
