The amount of people who would pay is going to be near zero in the grand scheme of things.

Next time you’re anywhere where you could discretely look at people’s phones, see how many of them run apps with ads. Most apps will offer very cheap IAP to remove ads, but people choose to not pay it. Vast majority of the users have already decided that their time wasted on ads are worth less than whatever tiny monetary cost it would be to remove them. Same thing here: Vast majority of the users have already decided they’re not going to pay to get rid of the ads. This in turn means due to how few people who would be willing to pay, it is not going to be nearly sufficient to keep the infrastructure required up and running, as well as keep the creators compensated for creating the content.
