I think you oversimplified the positions taken against scientific information. Certainly, there are notable cases of Republicans opposing an established scientific issue due to business interests, but they also oppose scientific matters when they are related to government imposition on the individual. For instance, a part of the Democratic party opposes vaccination because they believe they align with corporate interests, but you'll find Republicans that oppose them because the government imposes vaccination as a requirement on individuals. Both oppose vaccination, though it would seem to be a practice that benefits the companies that manufacture them. So it's not quite as simple as you present it.
