I really don't know how else to phrase my point: Marvel does the same things Fox does, but without the pushback from fans.
You want proof? (As if I haven't given you several examples) Show me where in the MCU you saw this?
What if I told you they took this guy
Took away his cape, powers, and origin and gave him a bunch of red tattoos and let Ronan beat his ass repeatedly.
If your opinion was "the changes that Marvel makes to the comics are better than the changes that Fox makes to the comics.", that would be ok.
But when you say " Fox makes changes to the comics and Marvel doesn't make changes to the comics", you are making a false statement. That's when I step in and say, no that's bullshit. The MCU is very much a different thing from the comics, using characters in different ways.
