Who were the other trustworthy developers who said nice things about the NX?
These days saying positive things about your competitor is nothing more than a marketing gag. Bonus point if it's an underdog. Unless the developer is saying "NX is so great that we will definitely develop a game for it soon!" I wouldn't give two shits about such a statement.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
