The interesting thing is how this will influence a referendum that wants to force expropriation of the largest housing companies ("Deutsche Wohnen und Co enteignen"). When the referendum idea first came up a common argument against it was "there are milder measures against high rents". Now that's what was tried and failed. I'm almost certain the referendum will get approved. There will likely be legal actions against it as well, but expropriation in the public interest is part of the German constitution, so legally it seems on good grounds.
