It is not an unfair thing. It is up to the developer if he/she wants to. Just like if you go into a resturant and they choose not to serve you. They have the right.

Developers are people, people have feelings, and feelings can be tarnished by being a nag.

So chill out and get a life. Do the mod yourself, contact GT or "politely" wotk with another developer to make it for you. You have choices so make one and do it!
