Not all scientists are government-employed. It may be a majority in some countries, but I would not disregard the amount of scientists employed in the private industries as well. They may not be involved in fundamental research, rather "applied sciences", but they are scientists nonetheless. Anyone who produces data through experimentation, analyses it, uses critical judgment and appropriate tools to make evidence-based decisions is basically, in my eyes, a "scientist", no matter the exact field of work.

Regarding your first point, the scientists who are not pragmatic will take severe hits to their reputations down the road. Data and methodology is what matters, not personal opinion.
