There seems to be some recurrent confusion about Section 230: how can it let a website be immune from liability for its users’ content, and yet still get to affect whether and how that content is delivered? Isn’t that inconsistent?
The answer is no: platforms don’t lose Section 230 protection if they aren’t neutral with respect to the content they carry. There are a few reasons, one being constitutional. The First Amendment protects editorial discretion, even for companies.
