I came across a short story a few years back. Probably post 2010.
I suspect it may have been on a forum thought it may have been a short story site. I thought it might have been a comment on on Charles Stross's blog but can't find it googling.
It was a somewhat meta story that I believe was inspired by some discussion about the standard "heroes journey" style stories like star wars etc.
The story opens with some kind of space battle, with attention focused on the fleet commander of one side.
They get news that a small group has managed to board one of their vessels.
The commander is alarmed and asks questions for some details of the infiltrators along the lines of asking whether they're a plucky young hero with a band of misfits.
upon confirmation he exclaims something to the effect that they're (not exact quote) "using [generic term for that story structure] against us!"
They refer to doing such a thing as one might about the first use of nuclear weapons in a conflict.
He then orders the fleet to stop firing and for all ships personnel to connect to their computers and to take whatever drugs they have to hand, it doesn't matter what drugs, anything, because (not exact quote) "we're changing genres, lets see how long plucky young hero lasts in cyberpunk!"
