What makes you think I can't handle disagreement? If If think someone is using shaky reasoning I am allowed to call them out, and use my actual knowledge on the subject to defend my point.

I am not saying google or apple have the best of intentions. They don't and that's why I use GrapheneOS.

Sandboxing is generally a good thing so long as it's done in a transparent way that can be controlled by the user. Hence the popularity of flatpaks, AppArmor and why GrapheneOS has even stricter sandboxing options than stock android. Walled garden ecosystems aren't good, and neither is spying. Apple is guilty of both of those, with google being guilty of the latter. You're painting all of these distinct things with the same brush even though they are basically cross purposes to each other. Different mechanisms are made for different reasons. The current state of mobile is the result of more than one decision made with different aims in mind. I am not saying that security is the primary consideration for all of these, certainly telemetry wasn't added for security reasons. Just that it's not as simple as you want to think. Nuances exist.

This is not subjective either. Someone somewhere will know the actual reasons these decisions were made. Even though we don't know the exact thought process behind them, we can still reason about what these mechanisms do and are useful for. Android itself is open source and these mechanisms are reviewed by other security researchers. You're just saying that to get out of the leg work of actually understanding the nuts and bolts of this stuff and what is and isn't supporting the end user.
