PlayStation 3 Kiosks Freeze on purpose?!?!

Destructoid is writing about his experience in the PlayStation 3 Kiosk freezing nature, saying that on different occasions he has seen the PS3 kiosk shut down. When he asked about it, some told him it's because it keeps freezing. Later on a Best Buy employee told him the locking and freezing of the console is intentional by Sony. They have made the PS3 locking intentionally to disallow people sticking in the shop playing it all day long! A second sales person also indicated to him the same thing.

I am not sure how true is that. Is it a cover up story or a real awkward decision. If it's a cover up story, we should see full list of bug reports, and if it's true, then that means if your PS3 keeps freezing at home, the shop have sold you the kiosk version of it! So get back there and get your money back.
