Well, again, it's not so much that freedom of speech is being curtailed but rather the ramifications of it. Someone could choose to attend a Phelps picketing of soldiers' funerals and plaster it all over the net. Can they be surprised if the company fire them the following day because of the damage it could do to their business?
Thats the problem with all the gossip and social media thinking, its creating monsters that want to tell others what to think or be forced into whatever someone else wants to make them to be. (it also creates lemmings, who pretend to think like or believe things they dont so they can either fit in, or not be attacked.
Good idea these days to make sure one doesn't live their entire life online also, and save unpopular comments for a pseudonym name or be ready to not care what others think or do.
