Naw, Elon blocked Catturd because Musk is thin-skinned.
While Musk has pondered some of the awful changes he's making to the platform for a while, many of the choices he's made have been impulsive. For one thing, his decisions to purchase Twitter and then back out were impulsive. So were his decisions to fire many staffers who knew how the platform worked and insult an Icelandic developer who was owed millions. Many of Musk's actions will have legal consequences, and that includes possible litigation over the platform's new branding. BTW, the decision to change Twitter to X and get rid of the bird was one of the stupidest things he's done to date. That should be part of a lesson plan for marketing/advertising students in the future.
