Threads was doomed to fail from the start. The reason is that it was not offering anything better than Twitter. Zuckerberg was just hoping to attract people who were not happy with the ownership change and censorship rules in Twitter. And in the end, it turned out that only a small fraction of Twitter users were open to Threads. And although Threads managed to enroll hundreds of millions of new users, the quality was missing. Most of these users were existing Instagram customers who just wanted to try out the new feature. And very soon they lost their interest in Threads.
Threads was doomed to die because it is a product of Facebook. Even though a lot of people uses it, Facebook has a huge army of those who hates this social media network for spying on people. I find it stupid to create a copy of huge social media platforms nowadays. Even though Zuckerberg has advantage over Musk in a fight, Musk already is leading 1:0, because of Threads fail. I just hope it was an expensive joke from Mark and Facebook, and with Threads, all the wanted to do is to prick Elon.
