So apparently SM works with the licensing part of FOX, right? SM argues that that the Alien, Predator and AVP titles are seperate licenses and he wouldn't be wrong. But this certainly doesn't mean seperate license = seperate canon. If it were to mean that then Prometheus would also be a seperate canon, no? It's like how Ironman and Captain America are seperate movie licenses but both feature in crossover films.
I think FOX is quite ambigouos about canon so that if people just want to enjoy Alien on it's own they can do that. Or Predator or AVP etc. on it's own they can do that. But when considering AVP it includes all Alien and Predator films.
I believe to truly render AVP 'non-canon' we'd need either an official statement from FOX or a third prequel film that cements the idea of David as the Xenomorph creator. But even then AVP could be enjoyed as it's own canon (not including the prequel films).
I'm with ya Turok and I give you props for clearly expressing your arguements in a level-headed manner, even when you're copping lot of sh!tty response such as "AVP = non-canon because SM said".
