Personally I will never understand why Mega Man fans are angry at Capcom for killing Mega Man. With Kenji Inafune gone, any future Mega Man game would suck anyway, so no more Mega Man games can only be a Good Thing. Capcom are protecting you from their own mediocrity.
(And for the record, I hate Capcom for purely non-Mega Man reasons)
Sega fans and really all fans do the same thing. They get attached to branding, names, art, and basically everything that isn't the people who create games.
