It's still an ongoing war, but with Manifest V3, Google will have an advantage over adblockers because they will be in full control over the frequency of extension updates, how many ad blocking rulesets they'll allow, and perhaps when no one is looking, prevents those rulesets from targeting their own domains. The latter is the nuclear option that'll instantly piss off the whole tech world if implemented now, but perhaps slow boiled frogs won't notice it once the heat is high enough.
