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.

They regularly try to add things to break it, and uBlock's devs update it as fast as possible. They'll probably slow down on these breaking changes as it falls out of the spotlight and people slowly forget about it.

I had to clear cache and reload yesterday.
