Nintendo cleared 401 GitHub repos in one day, and never went near a courtroom

Anti-circumvention notices work on code hosts because they skip the two expensive parts of copyright enforcement. Nintendo does not have to name a defendant, and it does not have to show that a particular game was copied. The assertion is that the emulator uses unauthorized copies of its prod.keys to decrypt Switch software without authorization, which is a claim about capability rather than about any transaction ^[7]. Set the two outcomes Nintendo cites as authority against the size of the sweep: litigation has produced two usable results, one settlement and one default judgment, while a single day of letters cleared 401 repositories ^[8][13].

The Suyu number is 78 percent of the whole sweep, and it is a fork count rather than a project count ^[11]. That is the part with consequences for people who never shipped an emulator. A notice aimed at an upstream repository takes the network hanging off it, so most of the accounts that lost code were accounts that had cloned something once and moved on. Suyu's own maintainer announced in April that they were stepping away entirely ^[4], which means the repository best placed to answer the notice was already unattended when it arrived.

GitHub's stated posture is the only real friction in this process, and it only operates if someone shows up. One X user argued that Nintendo had targeted a non-functional MonoNX build with no decryption functionality at all, making that notice invalid and open to a counternotice ^[14]. Filing one requires an account holder who still cares about a repository they walked away from, plus a willingness to hand Nintendo a name and address. That is the calculation the sweep is really testing, and abandoned code fails it by default.

Another X user compared the effort to bailing out a boat with a teaspoon, noting that emulation projects with no connection to Yuzu already exist ^[15]. Right about the code, and beside the point about the venue. Source code is trivially rehosted; the fork graph, the issue history and the years of accumulated links are not. What the seven notices actually changed is the cost of relying on the cheapest host available: it now carries a revocation clause that a letter can trigger, and the revocation reaches downstream repositories whose owners never wrote a line of the thing being complained about.
