It's really not so amazing. Unlike other platforms, the PS3 gave hackers a good deal of freedom to do as they wished when it was released. It was only a few months ago when OtherOS was removed that people got pissed and actually started looking at jailbreaking it in a serious way.
IIRC, there's a class-action lawsuit against Sony for removing OtherOS.
I believe it was recently thrown out.
Citation? I the latest news I could find on google was that the nine or so class-actions were consolidated into one, and that Sony has filed a motion to dismiss, but nothing more that that.
Thrown out....in Australia.
It's clear from the vulnerabilities found that it is more the communities fault for not jailbreaking sooner (lack of need) than to Sony's futile attempts at protecting their console. I mean come on, using the same Random value for all ECDSA keys and signatures?
