Way to strawman my man. SMS is not the only mode of communication and SMS and cell phone communication in general fall under a whole litiny of laws because they are considered a utility along with landlines. This extends the constitutional protections for the first and fourth ammendment protections to them. Your initial suggestion was a fallacious argument to start because utilities are not wholly private corporations, and thus do not qualify for the initial discussion. I tried to save it by suggesting that alternative means of communication which are utilized that serve the exact same purpose as SMS and telephone calls but are controlled wholly by private corporations DO fall victim to arbitrary censorship and it is allowed because they are not subject in their business dealings with consumers by any state or federal oversight.
