The point was that people who have financial interests can still provide useful information for the community.

I wasn't questioning that. I have no doubt the information he is articulating is valuable, but who is benefiting more, us, himself or his client? Regardless of how pedantic I'm being, your point is slightly flawed and should be called out. I don't feel it's worth attributing merit to people's efforts without understanding their behavior first.

There financial interests are very different and thus the information they create can lean one way or another. One is a paid consultant and another is a full time salaried employee. The one makes more money directly by benefiting the client (Mueller) and the other one makes more by equity and control (Cutts).

When it comes to money, people are largely motivated by 3 things: control, equity, and cash (which all subsequently translate quite nicely into money/wealth) however, each one can manifest itself very differently. Someone who makes their living by advising clients has a very direct interest in cash, so it's more obvious that his/her behavior is in line with ensuring that cash goes into the bank first and foremost.
