No, just because I find the default Google experience in Android annoying, and I don't see why they should know everything about me. Thanks to ublock, adaway and pi.hole I don't see ads anyway.

What a disingenous question, yuck. No, whether ads are relevant or not was never the core issue, so that alone wasn't the cause of his actions (btw, doesn't sound like much effort tbh). The relevance of ads is just a symptom of underlying cause.

It can be looked at as cognitive defense. I don't want a hostile ad/surveillance system to charm me with relevance.

It actually makes me feel good when I see irrelevant ads. Because it means the advertisers don't have a clue who I am so my measures work.

Not that I see many ads because I block them of course. I even use a pihole to filter all my android phone traffic and it's very effective against in-app ads on android. In most cases even the whole bar where the ads would have appeared is gone so the app uses the full screen space.
