>>while some others wanted the fed to force social media to carry all content.
Social media has a legal liability exemption specifically because they agreed not to censor views. They are acting like a publisher now (and a monopoly) and are in violation of their own agreed operating conditions.
The have an exemption because they do not produce the content that is posted. However that doesn’t mean they are required to post all content.
Not that it matters because Net Neutrality is about having the government decide what is proper content. That is why leftist support it.
