Answer:
The author believes that the best approach towards free speech in the private sector is for the private entities to censor speech by their users.
Step-by-step explanation:
According to the author, private entities were responsible for the censoring of free speech not the state.
He went on to say that these private sectors have the rights to offer these regulations on their different platforms and make exclusions to certain speech of their members.
Evidence can be see in the third paragraph. The author implied here that private sector has a right to invoke the first amendment clause that limits speeches that are lawless, full of threat and obscenity.
