I don't use Android right now and haven't used Google'd Android for almost a decade. And I won't. If this is the hill I die on, so be it.
I'm not going to use any sort of hardware attestation, especially one controlled by Google. You shouldn't either, even if you have an unrooted Google-certified Android phone.
"Not using" doesn't make any noise. If you just "don't use", you will just use less and less stuff.
Google doesn't give a shit, but smaller companies are the ones using reCAPTCHA and that kind of shit. Consumers need to complain to those smaller companies. And citizen need to complain to their government, if those case. In the EU there is the DMA: https://digital-markets-act.ec.europa.eu/contact-dma-team_en.
What's sad is that the few citizen who care are often complaining against regulations. And it is the lack of regulations that got us here. We need antitrust, period.
What do you use instead? iOS?
It's all fun until you can't get paid because some fintech app doesn't work. That's why we need regulations. I don't see politicians ever going against an advertising company when they're customers.
