The main way big corpos are sponsoring os is hiring the developers typically. That comes with a whole lot of things that some people don't want to deal with, like changing your place of residence
I doubt that they allow you to work on a VM there. I saw only marketing and content jobs there. In Munich or Zurich they do have VM teams. Maciej is from Warsaw, he could do surfing in Munich. Armin Rigo is in Switzerland.
Sure, also much cheaper.
But Munich has no sharks, and the wave is much easier to catch, and it's easier to train 360's :)
The Zurich wave is not that good.
