Releasing open source software too soon

What is the moral responsibility of releasing open source software too soon? For instance, a close-to-complete product that hasn't been fully tested.

What is the expectation of the programmer? Wait until it is fully tested, or release to open source and then continue further development, testing, and advancements?

The fear is that software is open sourced and could potentially lead to issues for consumers.

Is this an unfounded fear?
