I miss PS1 modding days, where people took responsibility for screw ups rather than making all these excuses and trying to commit warranty fraud. If you modify the software, you violate the Nintendo EULA. The fact that they are ever willing to perform repairs on these wiis in the first place is amazing of them. Yes, there is a stupid tax involved, but you broke it, and you're asking them to fix it, why should they do it for free when you aren't willing to play by their rules?
Warranty Fraud and Return Fraud are possibly the 2 biggest things that annoy me...
