what you're against is piracy.
piracy of current gen games is what you're against. As a consumer I should have the right to purchase a game (software) and do whatever the fuck I want with it, if I want to emulate Tears of the Kingdom because it runs and looks better on my computer than on my switch I should be allowed to do so. I purchased the console and the game, they've received my business, they should no longer have a say with what I do with my stuff.
Nintendo themselves use emulators for their products, there is nothing inherently wrong with emulation.
No one is complaining about Nintendo's developers, they're complaining about Nintendo the company.
The company is garbage. Anti-consumer as hell, proactively fighting against video game preservation, bullying fans out of making passion projects, the list goes on.
Literally no one is mad at Nintendo for the games they make, they're infuriated because they make great games while the company shits on its own legacy.
