Do you have any knowledge to contradict this picture? Surely billionaires are as individual as anyone else.
I agree this sounds like a contradiction, and I'm curious to hear Sam's reply. Let's not pre-judge him.
The other side to rule of law is that the government can't punish you arbitrarily - they need to have an applicable law, and they can only apply it to you as written (including penalties etc). In a system without rule of law, a subject can be charged with wrongdoing on the whim of the ruler. That part is also missing in KSA.
Anti-Israel, not (as) anti-Judaism. Saudi Arabia and Israel have a rough history. I know plenty of Jews who safely do business in the KSA. That said, they tend to stay within the larger cities of Riyadh and the more-liberal Jeddah.
In other words, money and business >> beliefs.
I think you are kidding yourself if you think religion doesn't play a major part in Israel's relations with the rest of the Mideast, on both sides.
And elsewhere it's a complicated issue: Anti-Semites use that claim (anti-Israel, not anti-Jewish) as cover for and a dog-whistle for acting and talking against Jewish people; on the other hand. people criticizing Israel's behavior have been unfairly accused of being anti-Semitic. It's often very hard to separate the two motives based on objective fact. (And to make it more complex, anti-Semitic race nationalists, including at least some Nazis, have supported Israel because it fits their concept of national racial purity - 'Israel for Jews, the country I live in for <their racial self-identification>'.)
I would agree they're not "friendly", but I didn't use that word.
Israel and KSA both benefit from people thinking they hate one another. But they don't.
The world is just full of contradictions with regards to what is common public knowledge and actual reality.
