HAHAHA, Lose focus on GT6?! PD hasn't focused on any game they've ever came out with so i don't know where you came up with that non sense..
Keep hacking until PD gives up.. Let them know that this is a battle that's going to continue until people get what they want. The game is old and over the hill now. Same crap for the past 3 years..
You expected the game to change after release? Interesting.
Also interesting, if your opinion of PD is so low, why do you bother playing their games? If you recall the news article in which Kazunori-san talked about the first GT and how he only went home a few times in that last year. That is focus beyond the call of duty. Quite a few of PD's staff also sleep on site.
You may not agree with what they have made, but calling them unfocused is unjustified.
As for the second part of your post. As PD have already responded to the hacking, that is a sign that they will not give up, even if that means more restrictions. A lot of people wanted further customisation options, so how favourably do you think PD will look on continued attempts to circumvent their patches for a thirty month old game?
Give them the chance to change it in GT6 or GT7 if 6 is on the PS3. They clearly were not happy with the state of the options in GT5 which is why they were never activated. It also shows that they were happy to include broader customisation option but possibly due to the GT5 game engine, it couldn't be implemented in the way they were happy with.
If you incite further hacking, they might just say no to putting the extra work in and you'd have only yourself to blame.
Once someone with experience of working with the GT5 game engine comes along and says: "yeah, all of that is really easy to do..." I'll believe it. Until then, all of these comments about how easy certain features are to add, are just wishful thinking.
