Social media is the opposite. Abusive users of those networks operate at the application layer, and can spoil the experience of other users at the application layer but (likely) not at the network layer. So they moderate user activity at the application layer.
In each case it's about trying to ensure bad actors don't ruin other customers'/users' experience. It's just done in different ways depending on what part of the network stack the bad actors do their work in.
We've already lost the right to privacy, we don't have the right to not self incriminate, we don't have the right to be free of arbitrary punishment, we aren't presumed Innocent until proven guilty, and we don't have unlimited free speech.
Do I think this as it should be? No. We exist, as humans, on the internet and therefore should have human rights.
The web is nearly entirely privately owned, which makes answering this question difficult.
On one hand, the web is where we do 90% of our communication these days and losing that right seems like losing most of the first amendment.
I’m convinceable either way. Did telephone companies have a right to censor land line speech? Should they? Should ISPs be able to censor? Should cloudflair? AWS? It seems like industries like ISPs should be regulated to be “dumb pipes”. But where social networks fall is less clear.
