The way I understood the current situation is the following:
Image for a second a piece of paper, there are two overlapping circles on it. One represents the people who want to run Linux on the PS3 and are trying to hax0r it. This circle is about the size of a quarter.
The other circle is for the people who want to pirate games and cheat AND HAVE THE TECHNICAL SOPHISTICATION TO FIGURE IT OUT THEMSELVES. The diameter of this circle is roughly the same as the Linux camp.
Basically, you have a very small group of people, who's only motivation for hacking the platform is Sony's removal of the boot other OS function. This group of people then gives away the plans for their hack, and thus enables all the people from your 50m circle who can't hack a PS3 on their own.
Claiming that the Linux crowd is irrelevant here, ignores the fact that one motivated person can release an exploit which will work for everyone, and I think the Linux crowd has a much higher ratio of people who might find those exploits than the crowd of wall-hack/aimbot enthusiasts.
Cheers
