... You know, I think it's the exact same problem with Spider-Man and Batman - in many ways, both of them arguably STARTED as loners (although Spider-Man much more than Batman), but they've both built up MASSIVE casts of supporting characters since then, so whenever some dumbass gets it in his head to "restore" the characters to their "iconic" state, he has to come up with some rationalization for keeping these characters' friends and families and teammates at arm's length, which leads to ALL of the characters involved looking like stupid, insensitive assholes.
HALF-measures make it even WORSE, because that's how you get idiotic developments like Peter telling his secret ID to the FF and the NuAvengers, rather than HIS OWN FRIENDS AND FAMILY (really, Peter? MOCKINGBIRD needs to know who you are more than AUNT MAY? REALLY???)
