Not really the case for Android, you skip the google account setup or the amazon account setup if you are using a fire tablet and continue using the device by sideloading whatever APKs you want. Most of the times the APKs that depend on Google Play Services will continue to work fine.

I skipped the amazon account registration and directly sideloaded the Google Play apps on my fire tablet.

Even for Google TVs you can skip the setup and use the TV as is. You can sideload APKs on this as well.

AFAIK, the account setup/login circumvention is not possible on fire tv sticks/google chromecasts.

You can take a very old android device factory reset it and continue using at as an offline only device without the blessings of google or amazon. (Except FRP devices)

But that is not the case with Apple, you need to connect it atleast once to the internet to activate the device.

Is this possible even if the account is locked to the device (FRP), which is often the case?
