I love that subscriptions in the US are (usually) immediately cancellable. Germany is the wild west of predatory subscription plans, and unfortunately the legal framework weighs heavily in favor of the businesses issuing these contracts and not the consumers.
To elaborate - in the U.S., you can usually get out of a subscription by telling your credit card to cancel the payments (or cancel the card, etc). In Germany, it's not uncommon for them to start sending you to collections if you do that, since, after all, you never cancelled the contract properly. They're not technically wrong but it's still extremely customer-hostile.
