Affinity is set by default because the it will provide the best performance for majority of OSG applications. This might be a "terrible" reason for you, but the OSG development is motivated not by just focusing on one class of users needs or preferences, default settings we try to do the best for most OSG applications. Please remember, The OSG is extensible, if you don't like default behaviour in most cases you can adapt the it. In the case of threading ViewerBase::setUpThreading() and startThreading() are both virtual and as such are meant for the purpose of specializing them in subclasses from ViewerBase i.e. Viewer+CompositeVIewer and for users then to subclass from these if they wish.
