I'd agree with that. They are all dedicated developers and almost by nature they distrust anyone trying to manage, promote or market their concept. Stepping into that team with a shiny suit and holding a clipboard is akin to suicide. You can just look here at this forum to see an analogue of a similar developer grouping.
Whether they meant to create this or not, the primary aim of ReactOS at the moment is to create developers that want to learn how to build, analyse, document and investigate Windows itself, creating competent Windows o/s level developers.
As a training tool it serves this purpose. This doesn't help potential users directly but it is a real life use.
Being positive about it, it is growing fast in the number of contributors and the low level interest it garners. If you want to 'use' it then you have lower your expectations.
Being even more positive, if I look back at the o/s and development scene ten years ago I could not imagine how close we'd be to a VB6 or Windows replacement. Both seemed an unrealistic desire.
Amazingly, both are making serious progress.
