From my understanding, the current status quo is:
1. A platform can not moderate its content beyond removing illegal content that is brought to their attention;
2. A publisher can moderate and selectively cull what ever user content they like, but is held liable for any infringing content that breaks its ToS or the law.
This is a matter I strongly believe requires an update to relevant legislation and a clear / strong precedent that can be pointed to. It feels like social media (Twitter, Facebook, etc.) is trying to be both a platform and publisher when it suits them.
EDIT: Made the language a bit more neutral and closer alined to the current than the "should be". A child reply linked an article that is worth reading [1], however take it with a grain of salt, seeing as it's more opinion and interpretation of intent than a reading on application of the law as it is written. This issue has been simmering away long before 2016. It's only started to come to the foreground as the social media giants started moving closer to "publisher" than "platform". It would have been unthinkable to see Twitter, Facebook and Youtube "fact checking" and adding content below posts ten years ago.
I see this less as a partisan issue and more of a civil rights issue. I don't want to imagine a future where we have untouchable arbitrers of truth.
