A lot of people complained about JMS during Civil War. Of course, what they were mainly complaining about was that while like the rest of Marvel he showed Tony doing shitty things, unlike the rest of Marvel he didn't wrap it in a sycophantic aura of "he's hard man doing the hard things, it's so haaard being him, you should worship him". To JMS, shitty authoritarian behavior was shitty authoritarian behavior. And I love him for it.
And thus, he was the only person in Marvel to allow Steve to behave according to his longtime characterization, instead of being an inarticulate thug behaving like an idiot.
