Gaming sites have been in a feedback loop of rumor and fanboi/gurlism ever since the new consoles were announced.
Granted, after the EA DRM debacles I can have some sympathy for the fears, but people have been taking rumor VERY seriously and it's made for poor entertainment and shoddy journalism.
If anything, any company wouldn't be as crazy to do that after all the outrage/negative feedback they receive about it before launch. Releasing it after all of that - now that would be insane.
Activision might pitch that design for the game on all platforms, but MS/Sony/et al are certainly not going to pitch their own platform as handicapped vs its competitors.
The console flat out won't run a game without doing a copy-protection check and the whole thing is locked down right to the hardware level.
Jailbreaking a console to run pirate or homebrew content is often a major warranty voiding surgery operation, unlike a PC where one can simply replace the .exe file.
