• Meta’s Threads racked up more than 30 million sign-ups within about 18 hours of its launch, emerging as the first real threat to Elon Musk-owned Twitter, as it took advantage of its access to billions of Instagram users and a similar look to that of its rival.
  • Dubbed as the "Twitter-Killer", Threads was the top free app on Apple's App Store in the UK and the U.S. on Thursday.
  • Twitter responded on Thursday by threatening to sue Meta, according to the publication Semafor, citing a letter delivered to Zuckerberg by a lawyer for Twitter.
