no you dont understand. Its not that they have to found the right motivation its more than the ps3 is a monster in all terms. Also in security. In case with the Wii, the Wii will be only childs place but the ps3 will need 30 of 20 year old vet´s to get cracked in time of a half year.
So you totally do not understood any thing about hacking the ps3 and how it is a pain in the neck to get the system customized.
