This is a really good point - us “believers” probably don’t glance at the negativity because we know it’s (generally) incorrect, but how others perceive it can be hard to convince if all they read is negativity.
Consider that most people know a laptop runs an OS, so they can distinguish “Dell” from “Microsoft”, so I’m often baffled why people stuggled when moving from WinXP to Vista / 7 (ie a whole new experience… and often asking where to get a hacked version for free), but when I suggest putting <insert distro here> then they run away.
