NEW YORK — A First Amendment group sued Texas Governor Greg Abbott and others on Thursday over the state’s TikTok ban on official devices, arguing the prohibition – which extends to public universities – is unconstitutional and impedes academic freedom. The complaint was filed by The Knight First Amendment Institute at Columbia University, a free speech group in New York that’s suing on behalf a coalition of academics and researchers who study technology’s impact on society. The lawsuit said the state’s decision to restrict access to TikTok on official devices, as well as on personal devices used to conduct state business, is comprising teaching and research.
