A frustrating thing I saw online recently-- a layperson switched to Linux Mint and commented that it was frustrating to use and lackluster, given the amount of work that went into installing it. An experienced linux user was one of the first to chime in with <a wall of text explaining why, actually, you're wrong, it's not frustrating>
With all the Windows nonsense, regular people are making the effort to install a new OS, a task which the vast majority of people have never had to do and don't have the existing skillset for. Keep in mind xkcd.com/2501 here.
Instead of telling them they are wrong, that it's not frustrating (even though they are frustrated by it), either ignore or try to help. I'd think these were bots from Apple trying to capture any of the Windows==>Linux people by being jackasses to them on behalf of the Linux community, but this has been a stereotype of a Linux user for a long time.
