Yeah I know, but there's always accusations that they've been ignoring them in merchandise or in advertising and whatnot anyway. That's why i said "supposed", even though that wasn't very clear.
I think there's some truth to it, like how DK's Avengers Encyclopedia doesn't have entries for prominent Avengers characters like Beast, Wolverine, or Doom, although they are referenced. Or like how Thing and the X-Men are removed from the Secret Wars cover on this shirt. At least the X-Men still get love from Marvel in the comics (maybe not the FF) but there's something going on in merchandise.
