> Unlike online UGC service providers, bookstores can be forced to remove defamatory books in the US. There's a reason there's a law specifically for UGC service providers, and you cannot defend this while at the same time demanding that they get treated like book stores when it comes to compelled speech.
Sure I can, since the plain text of the law in question only removes publisher (which are not notice-based), not the notice-based obligations and liability of a distributor. As the article you cite here argues, the extension of 230 beyond what it says on its face to also remove those distributor-style liabilities is a strained interpretation that some courts have adopted that lacks support in the text of the law and is explicitly at odds with it's legislative history and rationale.
So it's quite easy to support the law that exists for UGC service providers and demand they get treated like bookstores and other distributors as regards notice-based removal of defamatory content because that's exactly what application of the law as written does.
The debate over 230 is not, mainly, about this one area where some courts have applied it out of line with it's plain text.
