X escalates legal fight against Nitter, ordering takedown of privacy-focused frontend

X Corp. has sent cease-and-desist letters to the maintainers of Nitter, an open-source tool that let users view X posts without ads or tracking, demanding the removal of its instances and code repository. The letters allege that Nitter unlawfully scraped X data and circumvented API restrictions, citing Texas and federal laws. Nitter's main site is now offline while its creator seeks legal advice, and other instance hosts have received similar notices.
