It's telling that they call out how much money the top earners on Substack and Podia are making, rather than how much the average or median creators on those platforms make. These types of platforms generally end up creating a small number of superstars who earn orders of magnitude more than the average creator, with all other creators getting a relative pittance.

It'd be interesting to see the payouts on these platforms evaluated on the basis of something like the Gini coefficient (https://en.wikipedia.org/wiki/Gini_coefficient).
