Says who? I hear this over and over, but there's no legal basis for any of this. It's horse-dung.
> It doesn’t, for example, allow blanket moderation for political reasons
Who decides what's political?
> Moderating one political viewpoint while allowing another isn’t good faith.
Define "good faith". Also, you missed the "otherwise objectionable" part of that law. What's "objectionable" to one platform may not be to another. If I run a message board for adherents of a religion that say, opposes gay marriage, should I not have the option to censor posts that support gay marriage? If I run a message board for environmentalists, do I have to let climate change deniers write whatever they like?
> shall be treated as the publisher or speaker of any information provided by another information content provider
Emphasis mine. I think that implies any information provided by themselves they're on the hook for.
GP was saying something else entirely. They were contending that if FB moderates or fact-checks even a single user post, they are now the publisher of everything that users post on their platform. Which is not at all how the law works.
Platforms are still liable for content that they author and post themselves. They just aren't liable for what their users post, even if they perform moderation or "censorship" on those users' content.
That said, I think most of their moderation is awful and their fact checking is ridiculous at best.
And the moderation exemption is very specific to types of content. It doesn’t, for example, allow blanket moderation for political reasons. It specifically mentions lewd/excessively violent content. It isn’t a blanket “moderation” exemption.
Also, “good faith” is explicit. Moderating one political viewpoint while allowing another isn’t good faith. Stop the Steal is censored. Many ANTIFA groups aren’t.
