That’d be great for people willing to dive in, but to me it just says that they don’t expect it to be around for long. You might say it shows they’re confident enough it will be around to offer refunds if it’s not around long, but nobody else launches a product and talks about it going away so that would make me think they they secretly don’t believe in it.
People will adopt a product even if they think it might not last, as long as it's a good deal for them. When MoviePass was offering their too-good-to-be-true plan of $10/month for unlimited movies, the subreddit was full of people talking about how it was too good to last. But they signed up anyway since it was a sweet deal!
