Musk fucked up lmao. He tried a publicity stunt, which was "buying" Twitter. But, he was probably adviced later that it was a terrible investment. So he tried his best to terminate or back out. At that point, it was too late. He had signed the contract. And thus, he basically got handed over a sinking ship, which he proceeded to fuck up even more and created even more holes. Thus sealing twitters fate once and for all.
It's a good thing imo. Twitter being gone might be a positive thing. But Elon fucking himself over with his stunts and slowly revealing to the world what he truly is, is actually the best thing to come out of this whole internet saga.
