Yuzu fucked up. This is about more than the decryption. Yuzu's actions (copypasta from a fine redditor):

• Massive patreon, to the point it has an LLC set to manage the money flow
• Early access releases are effectively SOLD, they fucked around with manifest/build files, abused GPL to go after some forks back when they were Citra, attacked other forks/emulators then benefitted from their work and even replicated their practices (like CEMU's patreon), etc
• Actively targets Switch competitors (Steam Deck, Android), to the point Valve once included it in a marketing reel
• Its presence on the OFFICIAL Android play store rather than an apk competes with Nintendo's own Android games (undermining both those and the Switch)
• Unauthorized use of Nintendo imagery
• Extensive telemetry, itself juicy data that could be sold for advertisers, on top of Nintendo's own built-in telemetry that's also sent
• Patreon marketing is heavily focused on games that broke street day release date, and even when they show some "restraint" it's just a release day post how much better the game runs on a platform that's not the Nintendo Switch, in the same launch period where most sales happen
• Progress reports timed suspiciously close to major Nintendo first-party releases
• ATTEMPTED to make a competitor to the Switch Online service, using files from an external preservation group, and it would have been a PAID service, and the subscription MORE EXPENSIVE than Nintendo's actual service (it was $60 something) despite smaller compatibility, for games still online, as a CLOSED-SOURCE FORK of a GPL PROJECT so that players don't actually set up their own custom servers to avoid paying Yuzu's pittance. When there was backlash, they REMOVED all traces of online emulation after they couldn't profit off it.
