Allowing 28 separate, politically diverse and motivated data regulators to litigate a vague law against publicly unpopular multinationals is a recipe for capricious and arbitrary action, but I believe that was rather the intent.
Litigating on this particular issue would be an incredible stretch though. Offends basic sense of fair play imo.
If Turkey gets EU membership, it would be a hoot to see how Erdogan uses this law.
