People convicted of drunk driving are being ordered to install additional proprietary software in their computers (mobile phones): specifically, the nonfree apps for Uber and Lyft.

The one for Uber spies on the user.

I wonder what the judge would do when the defendant has no mobile phone. I fear this judge might order the person to carry a mobile phone. Mobile phones' movements and usage can be tracked and monitored by absolutely anyone, so being required to carry one is a big injustice.

There are occasions when it is legitimate for a court to require someone to wear a tracker, but such an order should always be explicit, not camouflaged behind "always have a mobile phone."
