There would have been engineering cost to designing a better lock. Also, that's not their product concept. These are not locks for people who care about security, they are for people who care about iphone ecosystem synergy.

If you look at it a certain way, this isn't really a defect: when this lock gets bricked by a firmware update or recruited into a botnet, you won't be trapped on your porch for too long before your neighbor's kid can let you in.

But also, full agree on "our goal is to be better than an open window." I hope they don't extend a job offer to that marketing intern.
