Thomas, considered a conservative on the high court, made the point during a 12-page submission as the Supreme Court issued an order that rejected a lawsuit over Trump’s blocking of certain Twitter users from commenting on his posts before his account was taken down. The Supreme Court said the lawsuit ultimately should be dismissed as Trump isn’t in office anymore and was blocked from using Twitter, coming after the Second Circuit Court of Appeals had ruled against Trump.
“Today’s digital platforms provide avenues for historically unprecedented amounts of speech, including speech by government actors. Also unprecedented, however, is control of so much speech in the hands of a few private parties,” Thomas wrote Monday (pdf). “We will soon have no choice but to address how our legal doctrines apply to highly concentrated, privately owned information infrastructure such as digital platforms.”
