Why Would Fedora be Free ? Can it be Trusted?

[Chalonec Roger]

All,

I am looking at using Fedora at my work and some people are asking the
following questions or have the following concerns that I did not know
how to answer:

1.  Why is fedora free and why would people work on it for free? 2.
Some people are concerned that since Fedora is open source that they
don't know where the software comes from so they can't trust it.  How
can they trust it? 3.  How are updates to Fedora vetted and accepted? 4.
Does Redhat have any involvement with Fedora? 5.  Does Redhat use the
same processes in "controlling" fedora quality and releases as it did
the free versions of Redhat? 6. Ostensibly Redhat offered free versions
of Redhat Linux because they could make a profit on support.  Now Redhat
has built a market and Redhat is no longer free.  What is the profit
motivation of the Fedora group and persons/orgs who make software
contributions to it?  (By the way, there is nothing wrong with profit.)

Thanks,

Roger
