So let's speculate a bit about him, did he really manage to pull it off?
Musk wants to acquire twitter because he can use it for his own selfish desire maybe in promoting dogecoin rather than bitcoin.
He is certainly not offering that kind of money if he doesn't think that he will profit from it, but do you really think that he would spend 40 billion dollars as a way to promote Dogecoin, when he can do it for free on Twitter anyway? This would be extremely stupid move and he didn't make all those billions by being stupid. He for sure has some bigger plans for it and not to shill some some shitcoin.
Is it about the data that he could get? Will he use it for something like his new inventions, or is he planning to use it for something like space exploration or another business that he can profit from?I do agree that the amount was huge just for things like promoting Doge (but I think this is one of his many reasons why). He has something in my mind that he is the only one that can pull off. I can only imagine the data or advertisements he could use. Whatever the reason, I am hopeful that we will know what what he truly desires from Twitter rather than other platforms.
