> These hypotheticals seem awfully contrived. Well.. they're not. I've first hand experienced "what if they accidently charge you for who knows what" as I mentioned in my example and I recall many, many stories on HN regarding problems with subscriptions related to these "hypotheticals". Not to mention that the "what if you simply forget you even had a subscription?" is probably the most common, I doubt most people periodically check their credit cards history and given how many subscriptions an average person have, it's way too easy to forget you've subscribed to something - maybe in a heat of a moment or for "free trial" that required your CC and started charging you once the free trial expired.
