I'm not as much bothered by the software being non-free, rather making the ownership of either an Android or IOS smartphone a requirement for digital citizenship too solve the 2FA puzzle is something that worries me. We're moving in that direction in the Netherlands with our national citizen's accounts (DigiD: mandatory if you want to file taxes, gain access to your health care records, or handle your insurance digitally).
