The interview makes it sound like the GDKChan is in it for the experience while the Yuzu devs are in it for the money, even if he's polite enough to not say it directly.
Tbh I dont see any problem with being in it for the money and making a good software product. Good for both teams i guess, they both getting smth out of it and switch emu community gets 2 good emus, so win on both sides.
