Alex got 1 billion bc his case was a default, against all advice from lawyers. And the jury was like "Well shit, if he's not even going to try to put up a fight, let's male it a billion."
That's not like Roger.

The case was a farce to begin with, just like Rogers. Even if he is a piece of shit.
Alex could have easily defended many of the claims, and whittled it down to something financially manageable, if he just bothered to listen to lawyers and descend I to his paranoid delusion that he'd already lost. He did it to himself.
