This article is quite hypocritical. If you are going to single out Saudi money as immoral or let's say unethical, you have to apply the same meter to all countries. And this isn't just Russia which is currently being sanctioned hard but also notably China or some other ME and African countries.

Now, if you want to know my personal opinion, I am very critical of Saudi Arabia and if Russia and Iran are treated as enemies and sanctioned I think the treatment of SA should be the same.
