To block all these ads and tracking, I am already using DNS over TLS/HTTP, NextDNS with custom DNS block lists (including almost all CDN's, Google Services, fonts etc), ADblock Plus with custom lists, Ublock Origin, Firefox, extensive browser settings (blocking cookies or JavaScript unless whitelisted, blocking almost anything except images), isolating websites in Firefox containers, custom privacy settings for each website I have an account at, DuckDuckGo, iOS with only necessary apps and very strict settings, Arch Linux with custom settings, etc etc...
Yet there are still ads or tracking. And it doesn't look like it's getting any better or easier to opt out.
