We know that he is an overly hyped businessman, he does whatever based on what he wants but I don't really know what he wants by acquiring twitter. He was able to buy all the shares thanks to the financial strength he had, but anyway it was just an offer so I can believe that he might fail with his plan.
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. As he believes that twitter has the highest potential to be the platform for free speech around the globe, so he'll definitely use it for his own gains. But based on my research, the twitter boards will do everything not to sell twitter. So most likely, all the boards have agreed to decline the offer.
