Why are you being so pissy? Just install one of those extensions that block spoilers or block people on social media that are know for not respecting that if that's what you're so worried about. At the end of the day switch piracy is fairly niche, and for most people that can afford it simply buying the game is way easier that hacking your switch or messing around with emulators. While a PC that can emulate the switch may be more expensive than the switch itself, you still get a way better value even at the higher price tag. At the end of the day, just because you have an emotional attachment to Nintendo's characters and games doesn't mean that you owe it to them to worry about people who likely can't afford to buy the games in the first place. If you want to see the game do well, just buy it yourself. At the end of the day if other people like it they'll probably buy it too. Switch piracy simply isn't as convenient as just buying the game, so most people who do pirate Nintendo games are probably people who wouldn't buy them in the first place.
TL;DR: Block people who spoil if that's a problem for you, switch piracy isn't that convenient so most people who do partake are less likely to buy the game anyway in the first place.
