Don't get bogged down in something that you don't have any control over.
Fedora, the community project, is theoretically supposed to contain all kinds of software, it's not a product, it's not streamlined or polished, although it is a little bit :+)
A vendor distribution is a different story. It's a product line and certainly some of these characteristics described in the articles relate more to products.
These are very different things.
The nice thing about Fedora though is that you can experiment on it and learn about the system and the software.
Look for business opportunities in building software that integrates into a Linux vendors product line. Look to the vendors for leadership.
We are not going to talk about the arbiter but just know that there is a third character in the open source paradigm. This third person does some interfacing with the community, and with the vendors, from time to time.
