If Jack Dorsey & Elon Musk (who are friends) merely wanted to run a MAGA site full of fascists, they could have just bought Parler & saved themselves approx 43.999 billion dollars.
What they wanted was to cripple the sad remnants of investigative journalism, and the political left, which successfully used Twitter for political organizing, activism & messaging throughout the Trump regime.
Why would anyone who cares about either of these things go to Jack's #Bluesky project.
