I stopped reading at around page 15. So basically you're mad at Space Guy for releasing an add-on before yours, which happens to be using the foundation of his in the first place?
He even said i could use his shield script.
just give credit.
Let's say you've spent 3 years developing some sort of revolutionary instant messenger, and then someone else releases a similar idea before you. You need 1 year to finish it, but you could maybe take a bit longer, look at your competition, improve on their faults, add in features being requested by their users, and then release yours. You could simply take this as a means to make yours better than his.
