I think the ultimate issue specifically with Facebook is not that you shouldn't give people voices online, but rather that when the voices form small, tight-knit echo chambers with zero outside challenge, the outcome can be disastrous. I believe this is why the author calls it a "walled wonderland".

To me this is actually an argument against extensive moderation mozumder is suggesting.

Echo chamber is still an echo chamber even if you like the sound of the echoes.
