Jonathan Williamson has written a good opinion article on the negative effects of Blender fanboyism.
In short, the Blender community has a lot to be proud of. However, the community has one big downfall, it’s users. The majority of Blender users are friendly, responsible, and contribute to the community and the software in positive ways. There is, however, a small minority of users that do more harm to the community and Blender’s reputation than good. This group of users are generally referred to as the “Blender Fans.” They are the users that refuse to hear anything bad about Blender and will standup in blind support of it, regardless of what the issue at hand might be. As is common with these small minority groups, they also speak the loudest and often give a false impression of Blender and its community.
