I'm actually surprised it took so long considering they were seeking crowdfunding while openly advertising the piracy use case and raking in thousands of dollars a month (now $30,000 - wow). Patreon rewards can be construed as profit-seeking; Patreon even charges sales tax if you donate under a reward tier (they don't if you go through the no-reward custom donation flow). It's cool to hate on Nintendo for being overly litigious these days, and they deserve that reputation, but with projects where piracy is clearly the main goal, and a significant amount of money is involved, I find it hard to sympathize. Even if it's technically legal, it strikes me as parasitic behavior.
