This is not NOT WHAT OUR CONSTITUTION INTENDED.
This is exactly right. The founders never envisioned a system in which a "private" company can control so much public speech. To them, only a government would be capable of this.
Their intent was that Freedom of Speech would be guaranteed, and they would not balk at some silly argument that censorship is okay if it is accomplished by a "private" company controlling all the communications infrastructure.
It's time to declare the internet a legal "commons", and forbid censorship on it. (excepting those things which are already illegal.)
