I don't think they can legally do that, and if they did then why aren't more people on 7.0.1 having this issue?I think it's verry suspicious that like a lot of people are having problems with the micro sd card reader lately. Could this have been cause by software ? Bad nsp install or nintendo pushing crap to break our modded consoles ?
The only way a bad nsp could cause that is if it was malicious. But it's easy to check beforehand if the nsp is using safe permissions.
