This is a good point. If you have a complaint, you should be polite about it. Developers are human and if their customers are always rude to them, why would they want to continue working for SE? If they continue working for SE, why would they want to listen to customers who are always nasty?

It's exactly that toxic relationship that has destroyed WoW. The constant criticism led to people quitting or not working there and the ones who remained no longer wanted to listen to their customers because they are always nasty. Ignoring their customers then destroyed the game. We don't want to do that here.
