The warning sticker on hardware is also bullshit.

The TL;DR of the Magnuson-Moss Warranty Act is that if the manufacturer wants to deny your warranty claim, the burden is on them to prove that the owner's "unreasonable use" (abuse), neglect of required maintenance, or modification of the product was the actual cause of the failure.

For example, a car manufacturer can't use the fact that you tinted the windows as an excuse to deny your claim for an engine failure, but they could deny it for your failure to perform oil changes.
