That's cool, but the problem is most software is not safe to use unless it's actively maintained and offering updates from at least a security perspective.

So I don't consider that a realistic approach for most people, especially for something as mission critical as password management.

You just can't really expect proprietary software to be actively maintained indefinitely for a one-time fee. Add to the financial (and ego-) incentives to downplay security issues, I really don't think people should consider anything but open source password managers.
