Blame the organizations that built out PS3 server farms just for crunching numbers.
Edit- Aight y'all throughly convinced me it was actually Sony that screwed up linux capability for everyone by trying to subsidize their hardware. And actually those unrelated businesses were very smart to take advantage of sony's pricing. If the PS3 released at $1000+, it definitely would have sold much better and we'd have a linux-desktop only PS6. No more need for additional replies thanks.
