Nintendo has been cracking down on emulators this year.
I'm guessing it's because the Switch 2 will be a "Gamecube to Wii" sort of upgrade. Gruntier CPU and GPU, minor hardware changes, but same basic system. So Nintendo has been cracking down on Switch emulators so there won't be a zero day Switch 2 emulator.
Honestly, it's fairly safe. A probiotic food is already colonized/being eaten by micro-organisms and they want to keep other micro-organisms out. I've eaten a cup of yogurt that was a year past it's expiration date and only noticed because it was so tangy.
