Also not a lawyer. To be covered by Germany's consumer protection law, you need show that you are end consumer of a commercial product or service. I don't see how that would apply to YC/HN.
If you could pull that part off, I think you could take YC to court in Germany, and even achieve a favorable judgement. However, I don't see any way how you could enforce the outcome, except if YC has assets in Germany.
