The popular narrative seems to be that Yuzu had something to do and/or profited in some way from the Zelda Tears of the Kingdom leak, which isn't true. The Patreon-only Early Access builds could not play the game any more than the public Nightly builds could. Both versions needed an unofficial game patch for the game to launch, a patch which the Yuzu developers had nothing to do with. Yuzu developers also did not implement or work on any bug fixes involving the game before its official release. Perhaps you were alluding to something else, though.
