Isn’t the TurboTax / Windows monopoly with the IRS a similar case? Defacto standard gone monopoly for digital tax returns. I agree that the government cannot lock consumers into duopolies but you still have a choice to go and get a piece of plastic. They also really don’t have a choice if the objective is digital convenience —- outside of Apple and Google, there really isn’t any competition. If there were a proper, open mobile platform with no vendor lock in, I am sure NSW would support that as well.
