Tech firms send Supreme Court a warning

Tech firms are warning the Supreme Court that weakening liability protections for online speech could put all types of service providers — including those operating offline — at risk of costly, business-wrecking litigation. Companies and parties to the suits made early filings and statements in two cases that will test long-held practices in the tech industry based on Section 230 of the Communications Decency Act, which largely protects platforms from liability for people's posts.
