“Real artists ship”
No product worth using is bug free.
This is not correct; "If a product is worth using, then it has bugs." (P→Q) does not imply its converse "If a product has bugs, then it is worth using." (Q→P). Buginess is presented as a necessary condition of being worth using, not a sufficient one.
It does, however, imply "If a product has no bugs, then it is not worth using.".
That was exactly my point. The presence of bugs in a product (in this case Apple Maps) does not mean it should not ship. “No open bugs” cannot be the criteria for whether a product is ready to ship.
I think you mean, should not.
