iPhone is a mostly privacy-protecting damn good experience without having to de-Apple, but walled garden App Store. Jailbroken iPhone is a good trade off.

Android is a bad experience when you fully de-Google, and you can sideload apps, but Android apps mostly suck. And apps that wouldn’t otherwise be accepted on the store mostly don’t exist.

Best option until hyperbitcoinization IMO is assuming they will both be infinitely hostile and building impervious tools like web apps.
