Editors have publisher responsibility and are thus liable for what is being published. Twitter, facebook are enjoying the protection from the state from being responsible for what individuals say. they cant have their cake and eat it. If they want to censor they should become a publisher, which we know they wont.
It is us, the end consumer, that has the cake and is eating it.
With TV and newsprint, we had no platform at all, unless the media company shared our views or deemed our speech newsworthy. Even for innocuous speech.
With Twitter and Facebook, almost all of us have a platform that reaches potentially millions of eyeballs. That didn't exist 20 years ago - back then, we'd have to self-publish newsletters, or literally speak from a soap box in the town square.
That said, it is a balancing act, and I'm not certain where that balance point is (and it possibly moves over time too). But, the posts that have been shared from Parler were possibly illegal - they were planning armed sedition at best and a coup at worst - both of which are very much illegal and prosecutable. It wasn't just unsavory speech - it was illegal speech, that Parler itself refused to moderate.
Right now you could as easily make an argument that the real danger to the democratic institutions are being lead by the big tech platforms. Either they become a publisher with responsibilities or they allow for this to happen.
