X Platform Bans Signal.me Links: A Blow to Privacy?

Elon Musk's X platform (formerly Twitter) has recently banned links to Signal's "Signal.me" URL, preventing users from posting them in DMs, public posts, or even their profile bios. This move raises concerns, as Signal, with its end-to-end encryption and privacy focus, is a crucial communication tool for journalists and whistleblowers, particularly relevant amidst recent US government data leak controversies. While users can still share their Signal usernames manually, this added friction impacts communication and potentially threatens information security and press freedom. The ban signals a further tightening of information control on X, with the motivations remaining unclear.
