Russian oligarchs have become unpalatable, toxic. The social contract that existed between them and countries in the Western world that took / launder their money has been upended due to Vladimir Putin's Ukranian invasion. It wasn't always like that. There was a time when Roman Abramovich showed up in London with his loot and every last member of every establishment celebrated his business prowess, but above all else his largesse. He bought mansions, yachts, a very famous football club, and plenty of access. No one, nowhere, ever questioned origin of his wealth, and word got out.
