I also think it's not the best to directly attack them and others. Stating that GOS is better than others and how smooth it works can be presented in a better way. I'm not a PR specialist but disputing false claims maybe can be done in a better way without "sounding desperate". Sry not native English and therefore don't finding the right words.
GOS is strong and works nice and I I'm so excited about the Motorola cooperation. Keep on with this awesome work.
