Others Industries deal with Journalistic Integrity

It might seem that others, outside of Audio, also worry about Journalistic Integrity:

Isn't that an oxymoron, like "low priced high-end gear" or "knowledgable audio salesperson"?
Or "reader-oriented review"?
In this industry, a reviewer provides a stellar review for a line of equipment,and then becomes the U.S. distributor for the line. Twice. Three times.
