Do You Have to Get People to Sign Off on Your Courses?

Do you have to get people sign off in order to do those interviews where they are going behind a table? Ause this is something, again, i've thought about myself. So one of the ideas that i've had is, i've done almost to hundred episodes now ith the pog cast. One idea i had was basically go back to all the transcripts on the interviews and clip some of the audio,. And then basically do me pre ting a course, but taking insights from the people that i've interviewed. But would people feel uncomfortable if i start commercializing their knowledge and putting it behind ta pay wall? I don't think so.
