Nitter, an open-source front-end that lets users view X posts without logging in, received cease-and-desist letters from X demanding the service be taken down. Following the legal threat, the Nitter.net domain was shut down and is now offline. The takedown underscores X’s enforcement of its API and branding policies against unofficial access methods.
