The whole change to X, ditching the in hindsight brilliant “Twitter” and “tweet”, is imo a dumb move regardless. But the excitement over this potentional trademark infringement is largely media sensation and from people on social media who clearly know shit about trademarks or just want to get clicks/likes. As for not thinking it through, changing to X was the plan all along and it’s normal, fully expected, a given, that changing to something like X, the most popular letter for brands, will cause legal issues. Meta had to pay others to use Meta too. Microsoft paid for ‘xbox’ too. Etc. etc. As much as I agree with what an idiot Musk is, this just isn‘t such a big fuck up as today’s trending news suggests. Nobody thinks of Meta or Facebook when they see an X, MS nor Meta will be able to stop Musk from using X.com, at best they can get a settlement out if it that pales in comparison to the value of the domain name.
It’s not a matter of not thinking it through. When you bet billions per hand you play differently than someone playing with dimes.
