Mignonette, apologies, I realise now you meant Oscar the designer and not Oscar as in ott awards ceremony!!
Interesting thought that they want to transcend politics, that's possible too. Whatever their ambitions, I get the impression, overall that they (G in particular) want to use their visibility to try and make a difference in a positive way. However they achieve that, I think their intentions are very well meant.
Although I know people who work in humanitarian relief in Sudan and they didn't find G's input helpful.
