You don’t have to tell me that.
Everyone who is not an IP owner knows that.
Also it doesn’t matter if something is “abandoned.” It’s still got an owner, and pirating that thing is still against the law.
The law is what matters when discussing legal matters. Nothing else has any meaning at all. Law and precedent are the only things lawyers care about.
If Nintendo wanted to go from a company that is tolerated to a company that is beloved, they would stop this, but they don’t. They are happy to be hated if it stops piracy of their games, clearly.
