Idk about that, maybe indefinite copyrights would be but limited term is entirely fair. Like imagine you spend 5 years and $50M to develop something (random numbers here), then the next day someone just copies it and sells it cheaper since they had no overhead in copying your product. There’s no incentive to create if all it does is put you in debt, so we do need copyrights if we want things. However Pokemon came out in 96, that’s 28 years. There’s been very little innovation in their games since. And seeing as Digimon wasn’t sued it’s not about the monsters, it’s about the balls. But those balls haven’t changed in almost three decades so I don’t think the really have a case to complain
I mentioned it around them once, responses claimed it either never happened it happened but briefly and was ended.
