@delroth and the thing is it's perfectly legal to distribute those keys. Apple tried to keep their keys to boot macOS as a trade secret, but lost in court and their keys are even publicly available: https://www.rcfp.org/wp-content/uploads/imported/20120105_202426_apple_sealing.pdf. The argument that distributing keys to decrypt software is illegal has long been proven a myth. Nintendo had no right to tell Steam to pull Dolphin off the store.
