Your best case scenario is that hardly anyone attempts to follow in the footsteps of a resounding Oracle success, and that everyone in the industry is saddled with huge potential liabilities until a massive multi-year relicensing project can be completed to confirm who is committed to never trying Oracle's tactics when they fall on hard times. That is a doom and gloom scenario for anyone who takes legal threats seriously and doesn't have an IBM-class mutually assured destruction IP portfolio. It's postulating a series of events that leaves us with most of the software industry intact, but for the most part would still be a scenario where the only true winners are the lawyers.
