Contrary to your point, McIlroy is one of the few players who has an ethical foundation and is not driven by greed. Saudi Arabia is a deeply corrupt regime: The 9/11 terrorists were Saudis; the Saudi Crown Prince murdered one of his own citizens in a Saudi consulate and had him chopped into pieces. They lavish money on money-grubbing institutions and individuals to try and whitewash/sportswash their terrible human-rights record and terrible image. That's what the formation of LIV was all about. They bought greedy, pathetic trump and they bought a bunch of greedy, pathetic golfers who just wanted some easy cash, nothing more.
And after corrupting the already deeply corrupt gangster and the greedy players, they've now corrupted the disgusting Jay Monahan, head of the PGA, who, it turns out, is just a greedy a$$hat as well. He's apparently just sold American pro golf to the Saudis. Money/greed turns a lot of people into disgusting sellouts. McIlroy is not a sellout.
