Doesn't change the fact that they have taken something that was intended to be Alien, Unknowable, incredibly strong, and such a threat that it could wipe out humanity and turned it into a punching bag for the predators to look good against. Not only that but over time the predator keeps being gifted with new abilities to one up the Alien, like acid resistant blood and dominant DNA.
I'm of two minds on this, there is a rule of cool factor regarding AvP that is hard to resist. Sometimes they portray the Alien as able to hold its own but by and large they are just bug fodder for the hunters. The match-up does not benefit the Alien or the Alien franchise in any way. It perhaps even contributes to the idea that the beast is cooked.
