X (formerly Twitter)

X has eroded privacy protections under Elon Musk, making DMs unencrypted by default for free users and training AI on user posts without consent. The trust and safety team was gutted, reducing moderation by 70%, while 80 million user data points were scraped for AI training without opt-outs. This platform now scores worse than #4-ranked rivals in transparency, with a 2024 report showing it shares 25% more user data with third parties than the average social network.
