I would bet good money that people using an xtreme tuning OS like Atlas, are more likely to get their games from the pirate bay and their hacks from honest-bobs-totally-not-virii.com
For me, Atlas was just a way of installing my gaming windows install a little faster, because I didn't have to spend hours removing or disabling all the shitware, spyware etc. I was gonna do that anyway. I think it's just as likely that people using Atlas are just Linux/Mac daily drivers who consequently have a much lower tolerance for Windows' builtin malware, and so take efforts to make the little time they spend in Windows more bearable.
