Meta's Threads surpasses 50 million sign-ups in first 24 hours

In less than 48 hours, Meta’s Twitter rival Threads has surpassed 70 million sign-ups, upended the social media landscape and appears to have rattled Twitter enough that it is now threatening legal action against Meta. But even as users signed up for Threads in droves, with some clearly eager to flee the chaos of Elon Musk’s Twitter, the sudden success of Meta’s app could raise a new set of concerns. Meta has long been criticized for its market dominance, and for allegedly trying to choke off competition by copying and killing rival applications. Now, some competition experts and even some Threads users worry that if the new app’s traction continues, it may simply lead to the accumulation of even more power and dominance for Meta and its CEO Mark Zuckerberg.
