Nobody is forcing you.

That is not really true, I mean depending on your definition of "forcing". Okay, it's true, nobody is holding a gun to your head.

But depending on where you live, it may be impossible to use a taxi. It would be impossible to work at a lot of workplaces. I work at a university where thankfully faculty are not required to own a smartphone, but students are (if you do not check in for attendance with the university's app, you automatically fail the course). Soon here it might be impossible to have a bank account without a smartphone app. Any event that requires tickets, forget about it. We're also getting closer to it being a requirement to see a doctor (some doctor's offices here already do not allow any patients that haven't installed their app, and the number is growing).

There's a lot of soft pressure, too. The supermarket by us doesn't require you to install their app. You can pay cash without a smartphone...if you're willing to pay 2x the usual amount for groceries (which are already quite expensive).
