The ticket seller is just a ticket seller. Here are some quotes from Matthias Jabs interview which was taken on 20th of October:
"... It would also be attractive for us to play the last in Greece, or in Brazil, or in Paris, or in Los Angeles. We haven’t decided yet."
Greece sounds fine to me Otherwise, could you please wait until 2030, so that the crisis will be a bit over and we could afford to travel again....
