Germany doesn't have the same litigation incentive structures as the US - no contingency fees, loser-pays costs, and relatively limited collective redress options. Most German consumers aren't going to file individual €5,000 lawsuits over tracking pixels, especially given the legal costs and time involved.
Personally, I hope this gets picked up by a consumer protection organization or a well-funded litigation group. Germany has been gradually expanding its collective action framework, but it's still primarily driven by qualified entities rather than individual plaintiffs.
