The Federal Trade Commission (FTC) has issued warnings to ASRock, Gigabyte, and Zotac, stating that the "warranty void if removed" stickers covering screw holes on gadgets are illegal. The FTC sent letters to these companies, urging them to change their warranty policies and customer support practices to ensure they are not unlawfully threatening warranties. The FTC cited concerns that warranty coverage may be denied based on these provisions, stating that such actions would not be tolerated under the federal Magnuson-Moss Warranty Act. This Act prohibits companies from conditioning warranties on the use of specific products or services unless provided for free or approved by the FTC. The FTC has preserved online pages related to these issues and plans to review the companies' warranties and promotional materials. While these stickers may be legal in other parts of the world, the FTC is taking action to protect consumer rights in the United States.
