What people and authorities?

I stopped using these services and told people to contact me via sms or signal. No problems so far.

The people who won't make that extra step aren't worth my time because clearly I'm not worth their time.

> What people and authorities?

- Make bank account.

- Bank forces you to use their app for obtaining TANs.

- App refuses to run because "your phone is rooted", i.e. because you removed Google's crap.

- No bank account for you, sorry bro.

I have personally been through this shit. Sure, some banks offer using a physical TAN generator - but not all!

Fair point.

That is a situation where I'd move bank, use an iPhone or just allow GServices on my device.

There is certainly a point where you just need to be pragmatic above all else. Otherwise, you can still reduce your interactions with their other services as much as possible.

Have you considered just making your own bank?

Not sure what TANs are, but why not using a separate (SIMless) old/cheap Android device only for that?

In my case, unofficial communication channel for college/school/job. You can handle it just with offical email and classes or phone but since everyone is on 1 app and basically no one on any other you loose out anything which is not necessary but not helpful. And goodluck convincing a non tech boss or several profs to switch. This is kinda the issue with network effects.

It's not impossible. You just have to make choices.

Building management, landlord, local charities and residents association are using whatsapp and Facebook, good luck moving them.
