As someone with both a college level understanding of German and an understanding of law, it's basically a law creating a special type of lawsuit similar but different from a US class action, that Germany passed into law after the 2015 Volkswagen scandal. It tries to incentivize businesses protecting consumers through actual safeguards by punishing companies when they lack them, rather than a class action that arguably has the effect of pressuring companies to be even more misleading or confusing to deliberately avoid liability. How it does this? Probably gonna have to tap in a legal scholar for that one.
