Calling it Junk science is a bit harsh. I would say that the sponsoring entity (one of the German states) did force an intermediate result. This might turn out to be a bad idea, but is needed to steer the political decision process (the German states and federal government want to convene to make decisions about the lock down on April 14th).
The study has been widely critiqued, but dismissal is too harsh. I don't think anybody really has said that the main finding is wrong. It just might not be as strong. Instead of 15% immune in the area, it might be just 12% or 10%. Fatality rate might be 0.5% rather than 0.37%.
The study goal itself is correct and it is a shame that not every epidemiologist is doing exactly the same study right now all over the world. That the German CDC did not think to run such a study themselves since Covid-19 turned bad is a scandal.
