Freedom of speech is mirrored by the freedom to hear that speech. They are two sides of the same coin.
Freedom of speech is meaningless if no one is allowed to listen, or if listening is made so difficult that it doesn’t happen.
Government is prohibited from censoring speech by the First Amendment (which they routinely get away with ignoring). As I see it, this also means they are prohibited from keeping you from finding and listening to any speech you want to hear.
The Bill of Rights isn’t generally thought to apply to government-created corporations (which I see as part of government), but if your corporation censors or prevents people from listening, I’ll consider you the bad guy.
You have the natural human right to listen, with or without the First Amendment or any other document.
Governments and corporations have no rights; rights are individual only. Don’t violate the right to speak or to listen.
