It’s an old article, but I’m not surprised considering they also released a software update for the 3DS days after closing the eShop.
Which was a colossal dick move on their part. Much more so than usual. Shutting down Switch key extractors etc… I get - that’s their current line of consoles and they have a justifiable right to prevent “unauthorised” uses (much as you and I might ethically think differently). But for a console for which physical and digital games are no longer sold first party and for which Nintendo have no route to gain any revenue? That’s just nasty.
