Yeah, I think that's the proximate cause: lots more competition and more insecure academic positions leads to more ruthless interactions with colleagues, a term that itself might be getting a bit obsolete with the decline of collegiality.
If I had to pick one part of it that bugged me most, it'd be the constant need to attack and dismiss other people's research. Very few scientists these days refer to something like the "excellent recent treatment of the subject by Professor So-and-so", unless it's a treatment of a subject that doesn't compete with the author's own research. Instead, usual practice is to paint competing research in the worst possible light, and only grudgingly admit any related work that was actually on-point and good.
There was PhD Comics strip somewhere that jokingly listed phrases least likely to appear in a scientific paper, one of which was, "Previous work by X et al (2009) was actually pretty good!". Of course, it's not entirely because authors have suddenly become huge jerks; the incentives on them push in that direction. With many more submissions, reviewers have gotten much harsher about demanding that authors distinguish themselves from existing work and prove that theirs is novel and superior, which supplies an incentive for authors to trash existing work.
