I assume from your post that the "instructor" in question is an Authorized Instructor of The Golfing Machine, LLC, and publicly proclaims that fact. Hence, as an "insider", his words carry more weight and are particularly damaging to the movement he is part of and claims to support.

The quote below does not apply directly to the situation you've described, but it does make a point:

"If you work for a man, in heaven's name work for him! If he pays you wages that supply you your bread and butter, work for him -- speak well of him, think well of him, stand by him and stand by the institution he represents. I think if I worked for a man I would work for him. I would not work for him a part of the time, and the rest of the time work against him. I would give an undivided service or none. If put to the pinch, an ounce of loyalty is worth a pound of cleverness."

-- Elbert Hubbard

There is a not-so-fine line between being an innovative force for change within an organization (for the benefit of all) and being deliberately divisive and controversial within that same organization (for one's own purposes).

Sounds to me like that line was crossed.

Yes you are correct. He is an authorized TGM instructor G.S.E.D.
