WHY not make the original apple chargers cheaper so people won't have to use fake ones?
No one has to buy a fake one. It's personal choice. If someone wants to risk their property or life to save $10-15 then let's chalk it up to Darwinism. Also there are plenty of less expensive UL, CE, CSA, and ETL certified USB chargers on the market if one doesn't want to spend $20. You can easily get a non-Apple but lab certified USB 5v charger for $10.
It's not Apple or any other company's fault that some of it's customers willingly buy expensive products and then go Mr. Roper when it comes to a $20 replacement accessory.
If anyone is "at fault" here its the Chinese gov't for allowing dangerous substandard products to made and sold.
