The incentives are also not aligned here. You make money if there's more ads in the podcasts. In a world where there's no ads, your company wont exist.

So at some point, you'll have to start prioritizing making money ("proving your worth to users") and will start to make sure there are more ads in the podcasts, so that you can remove them.

And that is a lose-lose scenario. You will end up directly contributing to more ads in the podcast. This is called a second order effect.
