The White House has joined social media platform Threads, a competitor to Elon Musk's X platform. This comes after the White House criticized Musk for endorsing an anti-Semitic post. Major corporations like Comcast and Disney have also halted advertising on X due to concerns about posts promoting Nazism. The move to Threads, overseen by Facebook's Mark Zuckerberg, is seen as a shift away from X, with notable figures citing Musk's behavior as a factor in their decision.
