Part of the problem is that nowadays, people don't even recognise their accusations as such, but consider them benign, universally-understood downsides.

"Professionals tend to act based on financial motives" is among these. You seem to think it's just human nature, and don't even expect anything different. Yet ask any psychologist, and they'll react as the would to an accusation of murder.

That's because in their job, intentional deviations from the standard-of-care can quite easily turn into murder (or manslaughter/negligent homicide to be more precise).

Very similar: accusations against journalists that they are acting on behalf of some publication-wide agenda, take money from the subjects they cover, or write/don't write certain articles with an eye towards the sector's financial future ("The Times studiously avoids mentioning adblockers")
