Yeah, having the code become permissively licensed if the original developer goes out of business seems like a good compromise. That said, we can't make policy

Yeah, having the code become permissively licensed if the original developer goes out of business seems like a good compromise. That said, we can't make policy decisions based solely on what leaves one group (in this case, the users of abandoned software) better off in the hypothetical worst case. We need to balance that with what's fair for everyone (particularly upstream authors in this case), ideally avoiding that worst case if possible.
