>Sony (and the other console makers, to be fair) go to absolutely incredible lengths to make sure that people absolutely do not get to run their own code on these machines. And then they sue anyone that finds a way to do so.

Also, to be fair, PS4 is the first Sony's home console that does not run user's code. All the previous Playstations had such an ability in one way or another:

Net Yaroze on Playstation http://en.wikipedia.org/wiki/Net_Yaroze

Linux Kit on PS2 http://en.wikipedia.org/wiki/Linux_for_PlayStation_2

And the PS3, initially, came with the ability to install user OSs http://en.wikipedia.org/wiki/OtherOS
