It's not a team up. Spider-Man never teams up with any superheroes during the actual battles or even when he's tracking down the villains. He does it all alone. So I don't get these complaints at all. It's a shared universe. He's going to work with other people and that's perfectly fine.
If any fans should complain, it's captain America fans about CA3 become Avengers 2.5. Literally every other sequel right now is a team up except Spider-Man (unless Maguire and Garfield show up). So Spider-Man should receive the least complaints in that regard at least.
