Absolutely. To be crystal clear, I am discussing whether the technical & intellectual work produced as part of your (as commonly understood by the layperson) property and business, ought (as a duty) to be furnished by the creator/owner under some license to the broader world in some sense (whether by specific request or generalized publishing).
I argue that, generally, if said piece of property has no other encumbrance, then after some event or period of time, if this property is not providing value, the creator/owner should yield the property to the broad public, as their duty to society.
In particular, I am not asserting that they have a duty to make it useable or useful, or have a duty to do anything besides a tar ball or the moral equivalent. I am not asserting that it is always possible (encumbrances exist...). I am asserting the principle that our duty to society demands yielding this property up to the world at some point when we no longer find it valuable to own in any sense.
I am founding my statement of duty based upon reading too many papers from the 50s-70s where really interesting systems were developed, and then redeveloped years later, when the original companies had disappeared or discontinued the initial product. I think we could be much further along if the publishing of source was a commonly done thing.
