My suspicion to this day is that these schools were both a spy front and long-game propaganda, where they were teaching how to make news more western-aligned.
Why would BBC want to teach their methods in Russia? How do they benefit from that? How does Soros benefit from that?
Why does US benefit from every kid on the planet being able to name the avengers and instantly recognize Coca-Cola cans?
I'm not saying this is some grand conspiracy orchestrated by the elites - but projecting your power by making sure everyone is aligned with you ideologically and culturally helps long term, both in making allies and in avoiding wars.
