Nokia Drive, was available on the market place, for free. You just needed to find it and it would've worked.
The newer Nokia Drive, is the same as above, but Nokia has added a protection of sorts to stop the use on non-Nokia handsets. Removing that obviously makes it warez. That you cannot deny.
Are you linking this to the porting of touchwiz and HTC sense? Which AFAIK do not have any type of protection, they just lacked the necessary driver's / framework to function.
The difference is one has to be cracked and the other ported.
