> Wrong. The teachers aren't professors of any type, or student assistants, or even employees. Their classes don't give credit towards a degree. They're contractors.

From Miriam Webster:

affiliated, adjective, af· fil· i· at· ed ə-ˈfi-lē-ˌā-təd: closely associated with another typically in a dependent or subordinate position

What you are saying is like saying "I've taken car rides from Uber and from Lyft, and was never under any illusion that the drivers were affiliated with the companies"

If your organization sells services that are fulfilled by contractors who are vetted by your organization and branded with your organization's logos, then those contractors are affiliates of your organization.

Classic game that universities love to play where they hire someone but that person isn’t “really” part of the university. Happens with extension but happens in degree granting programs too with adjuncts.
