Not useless. It is like the missing printer driver for Linux Desktop. It makes the experience ugly, but this is not the fault of the Linux OSes.

Also the bank should not require apps (instead they can offer hardware key support or desktop apps) and in fact some - at least in Germany - offer a different authentication possibility. Also the app for the German ID is published on fdroid and does not rely on Google services.

I don't have a mandatory bank or gov id app. Where are you living?

We're moving to a world where it makes sense to have one cheap locked down phone with the society mandated garbage apps on it, and another device that you use for real computing.

Might be worth trying to get your gov to pin down the number of users or process to get gov id supported on any new platform.

They likely wont specify 100k people or 10% of population or whatever email/petition but it at least records the requirement that other OSes exist and requires a process to support

I switched banks and made sure it doesn't require Android/iOS. Many banks propose FIDO2 + SMS, even bank of america does.

I don't use bank or gov id apps, why are these mandatory? Country-specific?

Weird definition of useless.
