It exists to some extent around Linux, because "Linux user" is an identity that some people care about, but I dispute that there are "Windows fans" and "Windows anti-fans" the way that there are Apple fans and anti-fans. Using Windows just isn't core to anyone's identity.

The interesting difference between the identities of "Linux user" and "Apple customer" is that one came from grassroots hacker subculture and the other is the product of corporate marketing.
