Google could bundle a real ad blocker that used internal only apis.
That's the real dishonesty. Disabling the public API, claiming "because privacy", and ignoring the most popular use case for those apis.
Fwiw, Google isn't disabling any ability to use the apis to record, store, and forward, everything you do on the web. The only thing being disabled is canceling a request, based on live heuristics, before it happens. What privacy hole does that close?
