You can try to paint academic, research, technical and professional papers authors with that brush. I think you'll find they strongly disagree with that characterization and are fairly tired of pushing back on it.

They publish where their careers mandate. The publishers who own those journals know those authors don't have any meaningful choice. Not that that stops the flow of industry talking points and mischaracterizations.
