This is NewEgg's chance to either gain or lose 1% of its customer base. Since margins are so tight on computers, and NewEgg costs for software support will decline, isn't this a no-brainer from a business perspective?
I think their customer base of people who use Linux, might want to use Linux, or who are just plain disgusted by this behaviour is way way more than 1%.
Remember that the people who will be upset by this (techies) are the same ones who put NewEgg on the map to start with.
