It's not the functionality that it stolen, it's the path to the solution. The calories burned in design and testing. Ideas are just ideas. Bringing them to market is where the calories are burned and by aping someone else's design, no matter how simple, you are benefitting from their R&D, their calories burned, without compensating them. And in Procom's case the R&D isn't in the hardware so much, it's in the software and providing the functionality that the factory doesn't with the stock CDI. It's "value added." It's derivative but enhanced, not a direct copy. You're trying to oversimplify the issue. Just because something exists doesn't mean you can take it and do anything you want with it. You can make your own version and it can even be inspired by others, but you can't just copy it exactly.
