iOS is collecting for Apple, Android is Google, but Google is a advertising company. Our of the box iOS is probably better (keep in mind Apple is a closed garden and you cant really see the code). I run GrapheneOS for my daily driver. But I also have an iPad. With Adguard you can block a lot, including with the right host file Apple domains. You can also via ADB degoogle a Samsung or any other android device.
So android gives you more options when it comes go blocking trackers, apps, etc. iOS is probably out of the box a little better, but you have not much ways to lock things down.
This is really shocking. Add calyx vs grapheneos dramas and you wonder why the privacy community is not working better together. I love both sites, and I think they both have great value, but man…
