You have the right to speak, not the right to be heard.

If government prevents people hearing you speak, that's a pretty serious curb on freedom of association.

Nothing says you have to be broadcast or promoted and nothing says you can impose on people who don't want to hear you, but the government telling people they can't talk to certain other people is not the same thing.

Also, in another comment you said "This is also great for hiding and suppressing organization of social uprising. This would have totally suppressed all the BLM content this summer."

Is this sarcasm and you are contradicting yourself or do you actually think it would have been great to suppress BLM organization and protests?

Courts apply laws to new technology all the time. And in this situation, it is very obvious that the courts would rule government restrictions on social media, that make it illegal for people to broadcast on social media, would be unconstitutional.

> What can we try then

Well we can't ban people from using social media, or for broadcasting to many people. That would very obviously be unconstitutional.
