It's not difficult, however it does violate privacy. It is one more brick in the wall for requiring that all citizens own smartphones. And smartphones themselves are quite bad for privacy. When I frequent a business and they tell me use their smartphone app, my response varies from "no," to "I'm not downloading your fucking app." (depending on how polite the business has been)

100% of smart phone apps are bad. There are NO exceptions to this, by virtue of the fact that you must own and use the smartphone to access them. We stand to lose a lot when we finally lose this fight. (and I'm sure we will)

100%?

I once published an app to help people track their budget. It didn't even request any permissions, not even internet. How is it bad?

I wrote an app for a university to let researchers track bat sightings in caves and upload it to a database for population tracking. How is it bad?

Do I need a smartphone to use it? If so, then it's bad.

Citizens don't need an ETA. Only non-citizens are affected.
