RedHat choose to use and release GPL code and a requirement of that is
the making available of the source code. RedHat are good in this regard
and do this willingly with no great fuss.

A requirement of the GPL is to provide the source upon request - no
matter who requests it. As I stated previously, RedHat are good in this
regard and do this willingly with no great fuss placing it on their ftp
making requests unnecessary.

RedHat have always publicly stated its support for Open Source and the
freedom it provides. Hopefully no future events make them evaluate their
position.

Johnny would be best to answer this one.

However, I think you want to know if CentOS has any form of relationship
with RedHat Inc. - That would be a no.

This one is for a person in a specific country to check out for
themselves. RHEL and CentOS and separate entities and must be regarded
as this when checking against any individual countries laws for download
and usage.
