Lifetime plans is one of those dark patterns that for some reason is still considered legit. I can't think of a single lifetime plan that I've bought that have actually been lifetime, most have been sneakily killed by not updating the software anymore.
Good point! I mean, I don't know if I'd say that makes lifetime plans themselves a dark pattern. It's demonstrating a lot of faith in the company to buy one. Hopefully Beeminder is proving itself worthy of that faith!
