That quadrant is where basically all "Western" mainstream academia sits, and has for quite a long time, and they write an awful lot.

I am a little surprised that the influence of online "influencer"-speak and marketing, being so voluminous and evident in the things' writing styles, hasn't dragged them other directions, though. Nor the enormous amount of socially authoritarian social media posting. I suppose the former is so empty of actual philosophical content (or, indeed, anything of substance) that it might have little effect, but the latter... that's weird. Maybe they're down-ranking by tone (angrier = lower-rank) which would sharply elevate academic-style writing, assuring a tendency toward economically-left liberalism.
