Even with a version with web dependencies eliminated, which I am skeptical Roon would create with its last bit of capital or which its creditors, trustees, or investors would allow be created, this version would not make for a particularly great product. I suspect many lifetime subscribers would bail from that software within just a few weeks.
I also just don’t see this reliably happening. One has to understand what happens when companies fail. It is not always, or even mostly, a neat and tidy “good bye and thanks” type of situation.
Most likely, especially in a scenario where Roon has licensors and other trading partners (i.e. creditors interested in assets) in related industries,. you would be looking at a bankruptcy or other turnaround scenario where assets are maximized for value and sold. While Roon LLC would be in breach of contract for dishonoring lifetime licenses, some future purchaser of the software asset would not be subject to that obligation.
This means that when the company would be going through this process, it’s very possible that the release of such a final version would literally be contrary to law, because it’s not Roon management in control - it’s a trustee, or a receiver, or an assignee for the benefit of creditors, and the release of such a version would dramatically reduce the value of the estate for creditors, which is the primary, and legally enforced, objective at that time.
Thus, this idea that, on the way out the door, Roon could (1) release such a version as described or (2) that such a version would have any long–lasting value to lifetime subs, is a bit if fantasy and fiction without a lot of thought behind it.
The only way this would really work, and this is coming from an IP attorney who has been through bankruptcy workouts, would be if Roon had a legal agreement with lifetime subscribers that was currently in place, with this fictitious non-dependent version in software escrow, with automatic release to each such subscriber upon bankruptcy filing or similar event, and all of this has to be properly papered with references to Section 365(n) of the bankruptcy code, among other things.
Point being, in practical terms a lifetime subscription is the shorter of the lifetime of Roon or the subscriber. Sound of gavel hitting bench.
