Imo, he's taking responsibility. If as an individual you can deploy the most money in the world, what do you do with it? Twitter became a negative-sum game of people competing to debase themselves in service of narrative in exchange for nothing but the approval of others who had already done the same. Unlocking that negative cycle can release a lot of captive value for everyone. The best way to do that is to connect great minds and scale them based on their revealed desires.

I remember Musk offered to solve world hunger but the NGO people who said they could do it flaked when (pen in hand) he offered to cut them a cheque. The next best thing is to provide a platform for discourse so that smart people indexed on truth and reality can thrive and wield influence.

The opportunity is that Twitter just isn't funny, and as a signal of alignment to truth, that's a pretty honest sign it has become oppressive and that it has become a thing that most people just do not want. The controversial censorship on Twitter has been against humour, which makes Musk's play such an obvious win. As an activist target, Twitter has spent almost a decade contorting itself and spending a lot of effort to make itself suck, and it just needs to suck slightly less to be a benefit to humanity. Value for money, it's probably the most effective $43B anyone has spent in the US.
