the FSF position is that GPL is unenforceable without a single copyright owner, which is why almost all gnu projects, linux, canonical/redhat/etc projects have a CLA or something functionally similar

That would seem a bizarre position from the FSF, since it would make the license on combined GPL works unenforceable. Do you have a source for that?

main point is expressed here i think: https://www.gnu.org/licenses/why-assign.html

but also seems i was mistaken about the status of linux copyright, they actually do have distributed copyright, apologies

GPL maternally depends on copyright enforcement. Who would sue if an infringement is detected? All the contributors collectively?
