Paypal (as an example) only asks for the name and IBAN and they do identity verification themselves, by depositing (!) a small amount of money on your account.
But yeah, it's a very high-trust society. Of course any charge can be reverted via your bank app in seconds. But it's still a nuisance to have to check, so people are wary of giving it away.
It's not high trust society. In Germany service providers have easy and instant access to your bank account. Like TSA to your body on American airports. They absolutely don't trust that someone will voluntarily make monthly bank transfer, so I'd call it zero-trust system.
Telecoms, kinda. They will try to force this on you via contract. You can say no, but they will lie to your face that it's impossible. You can always get a pre-paid, too. I witnessed the same situation (forced by contract) in some Gyms as well.
Vatenfall and other electric companies, the government itself, banks, landlords, Hausverwaltung, all are surprisingly chill about which payment method you use.
But then again, Telecoms and Gyms are always trying to cheat and steal from you in every country that I lived, that I'd call this the exception to the rule.
