Nope.
If you where to purchase a car, then the manufacturer can't sneak to your house and install a power limiter without your knowledge.
I know it's a poor example but it basically boils down to that.
Whenever a change is occurring in a product you purchased, you have to be aware of it.
MS once did a silent update which flipped the AP 2.5 challenges (silent dae.bin update) which only affected pirates (now, the AP 2.5 feature is completely flawed as even retail discs can falsely trigger AP 2.5 checks due to scratches)
I believe Sony also pulled off something like that...
Not entirely sure..
Anyway, there was a lot of uproar from those things.
Now many people didn't care (they always where online anyway and didn't pirate) but it still is the same.
They changed something without your knowledge.
