Hoertest, generosity is a virtue, and virtues have long-term and short-term benefits. There's absolutely no need to be less than virtuous, ever.
There is little doubt in my mind that Dan's review will be beneficial to all parties, and mostly to XC.
Incidentally this doesn't take anything away from the idea that this is a competition.
It is a competition. The competition is to develop the best tech. And XC is way, way ahead on that front.
How we communicate, and how we treat others, is not where we compete. Treating others with generosity and respect in no way hinders our lead in the competition; in fact, it fosters goodwill, trust, mutual generosity, and encourages others to support XC. So if it has any effect on tech, the effect will be indirect, and mostly positive.
