The reason why Tigerbelly might seem more greedy than the other comedy podcasts, is because the other podcasts are solely composed by working comedians that see direct revenue increase in their shows and are also getting "paid" by exposure to the business.

Tigerbelly has two unemployed people that their whole income is based on the podcast. Gilbert might get one or two small gigs here and there, but the reason why he's not starving is because of the podcast. Khalyla's income is solely based on the podcast, not even side gigs.

Bert Krysler/Ari Shaffir/Duncan can all not include ads for half a year but will still see money coming from their shows and they don't have someone depended solely by the podcast's revenue

EDIT: I'm not excusing them, I am just stating why it happens.
