The analogy is wrong. It works like a law firm, again, because it operates out of a law firm.
Think of it like this: Fegan is the partner, Lash is the associate. Lash does a lot of the grunt work, fields phone calls, etc etc. Fegan is the guy who will ultimately hammer out the terms of deals, give advice on whether or not a specific offer is competitive, and actually give the recommendations to the client. Lash is reporting up as the sensory organs while Fegan makes all the mission-critical decisions.
Your argument is silly if you have any knowledge of how law firms work. I write a lot of letters, briefs, and pleadings. Those, for the most part, all get reviewed and signed by somebody else and filed under their name. Your position is that I am the client's lawyer and not the person who is supervising and signing my work. The reality is that we're both the client's lawyers, that's why clients hire someone who operates in a firm rather than a solo practioner: they get more man-power. Fegan's book of business is too large to operate by himself, so he associates with other agents while retaining the reins. Both Lash AND Fegan are agents operating on Fesenko's behalf.
The margin you're operating in is a pretty micro-distinction. Certainly not worth pissing someone off who's trying to give you good information, someone who might have commented on the Cleveland story for example. Don't ruin it for everyone else.
