From the complaint:

Apple’s computers, including its iMac desktops and MacBook laptops (“Computers”), contain a critical defect that has led to at least two deficiencies in the performance of the Computers (the “Filter Defect”). The components in Apple’s Computers generate a great deal of heat during use, and Apple installed fans and vents to cool them down. But Apple did not install any filters for the vents. As a result of this Filter Defect, the fans suck in dirt and debris that get stuck behind the screen, causing a permanent dark smudging to appear in the corners of the screens. If brought in for repair outside the warranty period (or if Apple refused to honor the warranty), Apple told customers that they must pay upwards of $600 to replace the entire screen. In reality, there is a simple and cheap fix for many of the Computers: the screen can be removed by a suction cup, and then cleaned with a soft rag. Despite the existence of this inexpensive fix, Apple continues to charge non-warranty customers $600 to replace the entire screen.

One part of this is the design decision, a “lack of filters”. But another part is charging $600 to remove and clean a screen. That second part seem egregious, if true.

Looking forward to seeing Apple’s response on this.
