Wait, wasn’t it the other way around? There was that fail0verflow slide about how the PS3 took unusually long to crack if you count from the release, but essentially the same time as other consoles if you count from the moment one couldn’t run other OSes on it.

I don't remember the specifics, but after the keys were leaked (this would have been about a year after OtherOS was removed?), Sony managed to both release a firmware update that disabled homebrew, as well as block new releases from running on the old, hackable firmware.

That new firmware lasted for more than a year, too.
