On the location, I just followed the Rx.Net grouping here. It makes some sense as ConnectableObservable is just a wrapping around a Subject and its source. It does indeed extend Observable, but then so does Subject, and that is also not grouped under Observables. I would be fine with both ways of categorization.

On the copyright, I am curious what the idea is behind this policy. Maybe I understand something wrongly, but I would expect contributors to put their own name on their contributions instead of Netflix's. Is it that Netflix wants to have full copyright on all the code to be able to relicense it?
