In Germany, this sort of thinking is the reason you can't release anything into the public domain. People are presumed to be too stupid to be trusted with the decision to renounce their copyright and so they are "protected" from this possibility.
Have you ever been conned into releasing something into the public domain? Me either. Its not a real problem. But signing over the rights to some corporate party? That happens all the time, and is permitted in Germany. Germany is being very stupid here. They're letting abstract reasoning about principles blind them to common sense (many such cases in German history.)
