Captain America and Bucky have pretty much had their origins and histories altered to have been created and controlled by the Outer Circle since the beginning...even going so far as to change the origin of the Shield from a happy accident that could not be reproduced to being purposely created.
Monica Rambeau is now maybe a mutant from that scene in her recent LS
The Black Knight is not able to control the darkness of the Ebony Blade because of being honorable, noble and all those other "knightly" traits but because he is kind of mentally messed up.
And now in Hellcat Patsy has seemingly had some sort of demonic influence throughout her life.
Add in the disrespect that some of them (Hawkeye, Ant Man and Black Knight) seem to be getting crap from people who were friends and allies who used to treat them with respect.
And for Honorable Mentio...even though she in not such a long standing character...America Chavex and her not really being from an alternate dimension but from 616 and her moms were not that altruistic.
