I wanted to subscribed to Mediapart, one of the very very few independent news site in France. Everything is online (subscription, article) but the unsubscription with requires register mail! That's crazy, they are financed only by subscriptions (paywall, no ads) and not backed by any major media group/tycoon/the state, but they still rely on this dishonest practice. I read that you can unsubscribe by email, but if it's not written in the terms and conditions I'm not going to trust them on that. What a pity.
