Main reason the PS3 hasn't been hacked is that Sony was smart and let people install and run Linux on it.
So the people that usually hack consoles to run their own code on it don't need to hack the PS3 OS because Sony gave them something to play with...
So basically for once only the pirates are trying to crack the machine because most of the homebrew folks don't need to.
And usually the homebrew folks are a lot smarter and better at it than the pirates....
