To not reward speech does not equal suppression of speech.

Freedom of Speech does not entitle anyone to get rewarded for their speech.

Correct me if I'm wrong, but the ACLU article says nothing about getting paid for ones speech, does it?

They do not say, that in order for your speech to be free, you have to be paid for it no matter what, or else your speech is suppressed.

On Hive, speech is still free.
