This isn't inconsistent at all with the premise we're discussing. Academics are happy to make a stink about _external_ influence on their research, influence that runs contrary to beliefs dominant in academia[1]. Bitching about the Trump administration isn't going to lose you any friends in academia, but bitching about forces internal to academia, whose sympathy much of academia lies with, is a whole different ballgame.

(Note that I'm referring to the opinions of "academia" fairly carelessly here for conciseness, when I mean things like "the dominant opinion among the individuals making up the departments that affect an academic's career")

[1] Note that I'm not making any statement about academia being left or right specifically. Ie, I think the OP comment of the thread may be right about these forces being sometimes lefty

To write papers academics need to get grant funding. That's where the bottlenecks are going to primarily be.

That said I've read a whole bunch of essays by scientists whose research couldn't be published for explicitly stated ideological reasons over time, like this one:
