My concept with entering agreements has been:

I don’t have the time nor the immediate expertise to do this myself, so I want to hire you to do it for me. In return for bringing advertising to our podcasts, you take a generous 50%.

But this power dynamic doesn’t exist.

Instead, it’s more like:

Since I lack the resources and the necessary skills, I’m forced to rely on your services despite the terms being unfavourable. For which, I reluctantly agree to surrender a substantial 50% of the revenue.

I don’t know if it’s possible for but the largest creatives or artists to upend this dynamic.
