The reviewer's income is and should be no one's business. Also, how he or she acquires a component should not be anyone's business either. Once it is asked for in a review though, it creates an impression of bias, in my opinion. That's all.
A condition of wanting something usually means that we also like it. But if we like two components roughly equally, we usually buy the one that is less expensive. Now in the case of a reviewer, are we to assume that his/her reference system is comprised only of the components that he/she gets the best accommodation deals on? What does that tell us?
