I did not think I should pay to get the GSX v2 full, as I already have a key to the "old" GSX.
Let's make an example:
Suppose YOU worked for us, FULL TIME, for about a year, modeling countless of jetways, texturing them, then modeling and animating passengers, and you also made the coding that made all of this possible, and when it's time to get paid, I would reply to you something like;:
"Sorry, we can't pay you, since we decided to give your work away for free"
