Fair point, but then I think my other reply makes sense here: if you believe that twitter's is "unchecked", you have to first admit that the US is a failed state. There's no other reasonable argument I can find where the US government would be unable to enjoin twitter from doing what it did.
Either that, or what twitter did is perfectly in line with civil liberties as defined by pretty much everyone. They exercised their right to free association. What law would you create to enjoin them from having done so?
