How can you exert your constitutional rights if the government allows companies to create/purchase/monopolize every avenue in which to express your rights? What if you had to pay a toll to utilize corporate paid sidewalks and roads? How could you protest the government? Likewise, the internet infrastructure we have today was created by the government, so it only make sense that the fundamental rights we have protected by the constitution be respected here as well.

I don't understand why many liberals defend a corporations freedom to silence speech but get angry when conservatives in the government do it. Six of one, half dozen of the other, it's still speech being silenced by someone more powerful than you. But one being a corporation and one being a politician doesn't change the fact that both limit freedom of speech protected by the constitution.
