Media in general is poor on declaring any and all bias of their various interviewed "experts".
Quack doctors spruiking amazing new treatments (that they hold shares in).
Automotive experts promoting car brands (that they receive advertising and influencer dollars for).
etc.
One thing I've seen a bit in Norway, and which is relevant this month, is opinion pieces by "concerned parents" that get their writing into national news, but a quick search show that they're often head of some bigoted organization. Of course they should be entitled to their opinion and be able to express it as any other, but the news papers not disclosing this is unethical imo.

Doctors commonly have kickback arrangements to prescribe specific medication. Sometimes it's the correct course of action they just always go for the particular brand, other times it's the wrong course of action but they prescribe it anyway for the kickback (the OxyContin scandal comes to mind).
What you're seeing there is churnalism; journalists just want to get a piece printed and move on. Sometimes the whole piece comes from a source that benefits from the piece being printed, not just the expert. https://en.wikipedia.org/wiki/Churnalism
Sometimes the expert benefits just by being in the news, see for example NPR banning the expert they quoted 77 times, law professor Carl Tobias. Mainly because he'd write to them offering his opinion on the topics of the day, and as he is a law professor, even if the topic isn't law, NPR journalists couldn't help but accept his quotes to pad out their articles. https://www.mediaite.com/media/nprs-new-rule-for-2026-stop-q...
