If that's a reference to the protections under section 230 of the Communications Decency Act, it doesn't work that way. The whole point of section 230 was to say that being non-neutral does
not subject a platform to liability for content supplied to that platform by users.
I'm not sure why, but a lot of people seem to think it is the opposite: you have to be neutral to be protected. There was a court case that ruled that way before section 230. Congress wrote 230 specifically to reverse that.
