The point about Saudi Arabia having opened its laws and practices up to scrutiny in US courts by forming a sports league (as a sovereign nation they would have otherwise been able to dodge any subpoenas or data requests about this stuff) is interesting.
I would wager they realized they took a bite of a sour apple when they sued the PGA, and decided to sell on the cheap before having to concede at court to keep their dirty laundry hidden. And the PGA guy was like "Fuck, I'm doing this deal without talking to any lawyers, because FUCK lawyers and all that bullshit."
Now, he's going to learn the hard way why it's cheaper to pay a lawyer for a couple hours of advice up front, rather than hundreds of hours after you get in trouble.
OR if he really does have that clout, he can pay off the right politicians and the FTC will drop it. But the FTC under Biden has actually been doing their jobs, so that might not be an easy way out
