Elon Musk is asking Twitter’s users to decide if he should stay in charge of the social media platform after acknowledging he made a mistake Sunday in launching new speech restrictions that banned mentions of rival social media websites. Won’t happen again,” Musk tweeted, before launching a new 12-hour poll asking if he should step down as head of Twitter. The banned platforms included mainstream websites such as Facebook and Instagram, and upstart rivals Mastodon, Tribel, Nostr, Post and former President Donald Trump’s Truth Social.
