It drives business people insane, that people who have enough disposable income to pay to remove ads, are exactly the high value customers that they can charge more money to advertise to.

Once you have a ‘no ads’ tier, your advertisers know that the only people they’re getting seen by are people who don’t spend money, and they won’t want to advertise with you. But if you make a special “here’s an audience who piss away money like it’s going out of fashion” tier, they’ll triple their spend.
