It's next to impossible to refute the way someone perceives something whether the changes be major or minute, but on the basis of factual evidence... that's an outright lie.
You mean GTR, GTR2, and GT Legends - those titles?
I have the strangest feeling you didn't read the writing on the wall. I'm not mocking you or anything of the sort, and if you were unhappy with what was being presented you definitely should have gotten a refund. Having said that, I still can't shake the feeling that you simply couldn't read the writing on the wall.
You were playing a game that hadn't even entered a beta stage yet (and still hasn't), so you knew full well what you were getting into and how much work would need to be done.
So, why? That's an honest question being asked.
I've been a member since January, 2012, and your insistence that the title has only undergone "little tweaking here and there" would suggest to me you had already formed an opinion of the game and its underpinnings long before you actually played it and steadily refused to see anything outside of that.
