I get that you want to send a message, but what problem does moving to iOS solve? You have the same restrictions, in fact even worse ones, with way fewer options for accountless downloads.
This is what Forbes had to say about it: https://www.forbes.com/sites/johnkoetsier/2021/10/19/apples-...
They're not the same. Google generates ~80% of its revenue from an ads product built on user data. Apple has an ad product which generates ~5% of its revenue (mostly from App Store ads), collects far less info¹, does not share user info with third parties, and lets users turn off personalized ad targeting with a simple toggle².

¹ (because that behavior supports their primary sources of revenue)
And apple will chase that revenue if it sees the opportunity. With their control over iOS devices, when they do, you'll be powerless to stop them.
It almost works, but app developers don’t test with it, and also constantly push updates. The end result is that you never know which app is going to null pointer exception on startup this week (looking for unnecessary, but missing services), or which one will hellban your account for fraud false positives.
Also, for anything that wants google services, reading lat/long from the GPS is flaky at best. (Usually works, but sometimes puts you at a location from last week.)
