Trying to recreate something each of us uses every day and make it delightful is a completely worthy goal. To say that a “keyless lock” isn’t a new user experience makes zero sense whatsoever - it’s a new UX by definition. The fact that it wouldn’t stop a SWAT team from breaking the door down is beside the point - they never claimed it would, and that wasn’t the goal.
Why is their passion for building great locks any more silly than the passion each of us has? They took a stab at it and it didn’t work out, and that’s too bad, especially since it seems to have been for business reasons as much as product reasons.
It’s ok to say it shouldn’t have worked out because it’s fundamentally flawed. But to cheer and mock the demise of a project a lot of people were passionate about, one that was dedicated to making a great anything, seems to me to be the antithesis of what a community of hackers and makers should be for.
