I think you are confusing freedom of speech with freedom of the press.

This site is a 'press' (method of publication), and the owners of this press are basically free to say what they want with it.

This also means they can place any restrictions they like on other's expressions using this press, just like a newspaper can choose to print some letters to the editor, and not others, and edit the letters any way they see fit.

Does this mean your rights to freedom of speech are infringed? Absolutely not. Go to any street corner and say what you like. Or, get your own press, and you can have complete control over its content.
