This warning is present, albeit in much smaller print, on all devices with a screen that you buy. The unofficial apple policy appears to be "repair starting from 1 dead pixel on iphone, 3 on ipad". Samsung has a policy which depends on the screen type: 1 for normal LCD, 3 for Super AMOLED, 4 for WVGA-resolution LCD. Every single manufacturer has this kind of clause, you cannot fault pine64 for this.

Though of course as it is a much smaller venture, you can’t hound a sales rep until they accept to repair it nonetheless.
