> What's he going to do with all that money, and what does he care for the risk it's bad or shady?

The thing that unites Ellison, Trump, Musk, Thiel and a fair few of the other politically active billionaires is the obsession with "legacy" - they want to leave their mark in the history books, figures which will likely be remembered and taught in schools in thousands of years similar to Roman emperors.

Musk is the most obvious with his obsession of settling (and eventually dying) on Mars, Trump is dreaming of getting a Nobel Peace Prize (if only to not let Obama be the only US President who got one), and the rest is hunting for the "invented AGI" crown.
