Any organization that, for whatever reason, actually does use a ps3 for OtherOS then they wont be playing games or using the GameOS whatsoever, and so this (and any future FW update) will never effect them because they don't need to update.
Any organization using OtherOS can still go online and use their OS of choice's browser to go online and their PS3's FW doesn't have to be up-to-date.
