Not sure why you think that government censorship is the only enemy of the noblest form of free speech. The government is the only actor restricted by the constitution, because the constitution's purpose is to set the structure and limitations of the government. However, the ideal of free speech is much greater and the enemies to free speech are, in today's world, much less often the Government and much more often economic or social. While it would not make sense to try to attack them through constitutional arguments, the ideals of the first amendment are a considerable reflection of greater ideals of free speech to which we should still strive. Why should we not exercise our own free speech to speak out against economic and social forces which try to restrict it? It is not a dilution of the term to apply it in this way. It has since its inception referred to freedom from all sorts of restriction. Bertrand Russell in 1922 wrote: "Legal penalties are, however, in the modern world, the least of the obstacles to freedom of thought. The two great obstacles are economic penalties and distortion of evidence. It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living. It is clear also that thought is not free if all the arguments on one side of a controversy are perpetually presented as attractively as possible, while the arguments on the other side can only be discovered by diligent search."
