I'm confused at all of the hate. Do I think Nintendo has always gone overboard with their lawsuits going all the way back to the game genie days, yeah. But, they've been consistent the whole time. If you try to make money off of their intellectual property, they're going to sue you into oblivion, period. No matter how much some things might annoy me, I can't get mad at that because I would act the same way.
As far as emulation goes, I think anything 2 generations back and older is free game, but emulation for games on current generation systems that are currently out and being sold is a bit much since it helps to quicken the destruction of an industry that is already eroding thanks to all of these big mergers. Pretty soon, the only new games that are going to be green lit are indie games and the ones that have the ability to bombard you with ads and do micro-transactions, because like reality tv, why build content that's good when you can put out something that is dirt cheap to create but you can keep on cramming it full of ads and rehashing it to have a nice steady stream on revenue on the books.
