I think the word "corporate" is a matter of symantics in the context of what OP asked. Ubuntu Desktop is managed and maintained by a Canonical, a corporate entity, but is not the primary focus. Canonical's primary focus appears to be their server sector, which is certainly financially driven.
Fedora can be seen separately from Redhat, in that while Redhat funds Fedora, the community maintains and supports Fedora as a separate project. There is a symbiotic partnership.
In the last couple years, I've tended to move away from Canonical. I'm not disappointed by their products, but I think financial goals should not determine innovation regarding GNU/Linux. This was a primary reason I moved from mainline Linux Mint to LMDE. I would feel the same about Fedora if I found out it was the same.
