I'm still waiting on the receipts for you to back up your fear mongering on this. So far you have been wrong every step of the way but I guess because you type something you think it's magically true right? Millions of people are playing Pokemon right now, there would be a lot of wiped SD cards if it was what you claim it to be.
And yet... there isn't. There is no factually proven case of this happening on a non hacked switch with proof that the MSD card also wasn't counterfeit. You should of learned this lesson after the Pirahna Plant hearsay but alas, here we are... You jump the gun and claim NAND gets fried then when that doesn't work out quickly change to whatever is the current theory being buzzed around social media when I can tell you if it was a wide spread issue that pokemon was wiping SD cards it wouldn't be twitter outrage news, it would be main stream media news.
