Governments make these things called laws. If you don't follow them they have people with boots and clubs that can take your money, lock you away and/or just rough you up a little when they take your phone to look what's on there.
They don't have to make it impossible to get the app, they might not even want to make it impossible! Because now instead of surveillance or not, dissidents (well, everyone) have the choice between surveillance and being a criminal that they can Protect and Serve(tm) at their discretion.
This is what the politicians mean when they say the laws of mathematics are below the laws of the country, and they're absolutely right. Don't bring tech to a legal fight, you will lose.
