It seems likely that some individual learned of the existence of the historic German urban guerrilla group which went by that name, and then heard the name again soon afterwards. This plucky wordsmith may then have named the phenomenon after the very subject which triggered it. If what you linked to isn't the guerrilla group, then what group is this paragraph referring to?
