Ublock origin and pihole make the internet a more pleasant experience for me. It has been suggested that I should feel some nagging voice causing guilt that I do not support the sites and apps I use that depend on ad revenue. Perhaps there should be, but there is not. Apple's position on this is just responding to demand. When wifi access points start offering built in enabled pihole by default those access points will sell well. Throw in a vpn to pipe your phone through it from wherever that is easy to use/automatic and "ads are useless" may become truth.
Edit: it would likely just cause a shift to self hosted ads, which is a dramatic improvement imo.
