Yes, it will spark discussions again, and certainly be tested in front of our highest courts, and probably fail in some aspects and send back to the drawing boards again after a few years, but I don't expect that much "outrage", at least as long as it remains a tool for few specialized cases.
I'm working in Germany (Berlin) and I was shocked by how often you see "cash-only" signs and how electronic payments are avoided on a privacy ground. Plus I saw the reaction from a German colleagues when it was a matter of communicating some personal data to a company that manages the salaries and I realised how Germans are obsessed (not necesserily in a bad way) about their privacy
Yet they (the Germans I've known) don't seem to give a second thought to handing out their bank account numbers to businesses for electronic payment purposes. Discount card use seemed to be widespread as well despite all the tracking that inevitably comes with it. I never once got through the check-out stampede at Rewe without being asked if I had a card. I met some wantrepreneurs in Berlin who were hatching discount/reward card schemes of their own, not something that would attract much investor attention here in the States, unless of course it was "the Uber of discount cards". No, stop, that's not an Idea.
The constitutional court is expected to rule on this in April based on an older complaint which makes it even more egregious that they start using it now.
