It is so hard to tell people about using Linux, how great it is, it's free, etc, and then you get to the name part and it's called 'fedora'.
Nothing whatsoever to 95+% of people, but perhaps 5%, most of whom one might describe as "very online", have decided to strongly associate it with a certain type of annoying guy prone to wearing them (they're more often trilbies, but whatever, the fedora is what's been "meme'd"), to the point that they would choose to be bothered or turned off by an OS named after the hat style.
