There was, for apps. There was this neat model where apps were put in the App Store, with a price, and people paid those prices to get the apps, and they didn't have advertising. Then people complained that the price of a latte was too much to spend on computer software (silly me, I still remember when VisiCalc cost hundreds of dollars). And lots of apps decided to compete on price, and there was a quick race to the bottom, with many apps "selling" for free. At which point, ads were the only way to make any money.The problem isn't VPN adblockers. The problem is ads themselves. There needs to be a new business model developed which isn't based on ads and clickstreams to generate revenue.
I'd much rather go back to the model where apps cost $3-$20 and didn't have ads. Maybe have some games continue with the "free with ads, $1-$10 one-time IAP to remove ads" model (as the available equivalent of a trial period). But it seems like the majority want apps "for free", so we're stuck with ads.
