I would argue that maybe CGL doesn't owe anyone anything, that they can be just as noxious as Harmony Gold and do nothing but squat on the rights, denying them to anyone else and forever choking off any further battletech progression...
But, the fans and consumers owe cgl even less, If that is the case. Our relationship is entirely transactional. If you want customers good will, money, and efforts promoting the brand, then there needs to be something that we get on our side too. Historically, that has been "a progressing plot and products related to it"
If this arrangement is no longer desired, if there's no longer any point in waiting impatiently all the powers that be have to do is make it clear that they are no longer interested in exchanging products for money, and I can go spend my money on bolt action and robotech tactics instead.
Complete, new, products too, not copy-paste jobs, repackaged leftovers like TRO3150, or pamphlets about planets with nothing of value left on them.
