I guess that can also be extended to things that can accidentally be suspicious. Imagine if Colonel Mustard, who “doesn’t have anything to hide”, let the police search their trunk and found a broken candle stick. Even though he wasn’t being searched for that in particular, now he’s a suspect in Mrs. Peacock’s murder at the gazebo (Clue reference).
Seeing a very popular and powerful $5 OS next to $100 Windows cards at the store would be pretty compelling. I guess their advantage would still be that all you need is a code to install Windows on many machines while you need to boot into an external drive to install Ubuntu (and any other OS).
