I don't disagree that Nintendo is trying to squash potential competition, though when digimon came out, Game Freak actually was the small indie company they pretend to be today, and wouldn't have had the resources to sue Bandai-Namco, even if they wanted to, and since this lawsuit is claiming to be about game mechanics, digimon has nothing in common with pokemon, except that there are cartoon creatures and you battle them in a (usually) turn based way. The original Digimon world for Playstation didn't really have any overlapping mechanics with pokemon apart from standard RPG mechanics. So the circumstances are radically different, which is why I used nexomon as an example, as it is mechanically identical to pokemon, but isn't seen as a big enough threat to warrant a lawsuit (Putting their game on nintendo consoles probably helped with that)
