I agree. As our society moves more to Internet-based communication we must consider how to preserve and apply the principles of free speech when so much of it is governed by private entities. Is free speech not a desirable trait? Is it merely something that racists exploit, and thus the move to autocratic private management is a blessing, a relief from the constitutional shackles that would compel, say, a law enforcement officer to beat back a mob intent on torching a KKK newspaper? Is that a better world?

Remember that these same principles apply to progressive views as well... which have not historically been as popular, and greatly benefited from free speech protections. I would say we would not be where we are now as a society without them.
