There are multiple reasons. You often don’t subscribe by credit card but by bank account (you authorize them to pull money from your account). This means you cannot cancel, only the company can cancel. If you want to cancel you must hire a 150€/h lawyer to take them to court and fight a lengthy lawsuit that you will lose. If you did subscribe by credit card and block it, they will hunt you down to the last cent. They have the lawyers and debt collectors while you don’t.

It's a good thing actually, reverting a SEPA debit takes two clicks. But indeed, cancelling payments is definitely not a way to get out of a contract.
