Well, yes, the probability that you will get sued into oblivion because the system of laws doesn't offer free speech protections could be seen as "commercial reasons". The article states as much.
A private institution censoring its own is very different than an outside entity forcing censorship via threats of lawsuits.
But the lawsuit here is private also though right? How do you separate an incorporated entity from a community? I don't know that this can be reasonably done.
"How do you separate an incorporated entity from a community?"
An incorporated entity is still a group of people and you shouldn't have to give up your speech rights to get liability protection. So, my answer is the same for a blog as a publisher. You either believe you were right or come to see you might have been wrong. If you believe you are right, but the lack of protection under the law allows others to crush you, then something is seriously wrong.
I think you're mixing the meaning of "private". A lawsuit is a part of the public law system.
Almost everyone self censors or society would be quite different. In fact, inability to self censor tends to get people in trouble or is seen as a sign of mental problems[1].
However, I cannot really say your wrong. I'm not sure about the meek or obedient, but I would go with stilted or excessively formal. Societies with massive self censorship are very scary.
I have noticed that societies with massive self censorship often have governments that enforce it with an iron fist. I'm not sure if there is a laid back government with a society into self censorship.
