If it's so amazing that people only unsubscribe by accident, they'll certainly miss it quickly and subscribe again immediately. The practice of using "dark patterns" to prevent people from unsubscribing is utterly disrespectful.

Gave me a giggle, but yeaaaaah, no. XD

Let's be real. It's a dark pattern to make people give up on cancelling, rather than go through with it.

The more difficult something is, the more likely people are to give up on any phase of doing that thing.
