Well, if everyone has ranting screeds on their Glassdoor you'll blame the ranters. If only one company has a ranting screed, you'll blame the company. No one writes a ranting screed for not receiving feedback. Therefore no one wants to be that company. Essentially, we're in a stable equilibrium.
I feel you overestimate the amount of fucks managers and HR give about Glasdoor feedback from rejected candidates in Germany. No company I interviewed at gave any meaningful feedback(for legal reasons) or seemed to care about opinions of rejected candidates knowing recruiters are constantly flooding them with resumes from new potential candidates on a daily basis and also most rejected candidates won't bother writing feedback on Glassdoor because once you've been around the block a few times you realize it's the norm and you're basically preaching to the choir.

The hell they don't. The root post of this very thread could easily have been a "ranting screed" on Glassdoor if the poster was of a different mindset.
