Unfortunately I don't have anything besides anecdotal evidence but SFGate
did choose CentOS over RHEL. I've also been part of OS trade studies
where deployment costs trumped RHEL support and other Linux servers
distros won. This was for highly mission critical systems where I was a RHEL
advocate. Although I would also have advocated CentOS instead had it been
an option (for whatever reason it didn't make the downselect) since it IS
functionally equivalent, equally zero cost to other alternatives with exactly
the same RHEL advantages except support.
Within the DoD community, not picking RHEL/CentOS or SLES is sub-optimal
90% of the time.

But they don't do it for $20K per copy like I was paying for Solaris with
Silver support. Neither does Sun.
And...um...anyone who pays full retail for RHEL for any kind of significant
deployment isn't even bothering to pick up the phone. Yeah, if you only
need one or two copies you might pay full retail. Although if you only need
one or two copies you often don't NEED enterprise level support.

Well...I try not to use the word stupid in even semi-professional discussions.
At least not on public mailing lists. :)
Your statement may be correct in the general sense given folks will pay for a
commercial license for things like MySQL because they don't want to open up
their source but I don't think that RHEL is a particularly good example. Especially
since nobody wants to buy RHEL 5 Update 1 gcc as a standalone product and
wouldn't likely pay any money for it even if RH offered it as a standalone product
like Sun does for it's compiler suite.
However, given that gcc is free even Sun Studio now has an "express" version for
free. If you want "premium" support it's $1200.
I wonder how many folks pay $1200 for Sun Studio 12? More importantly, how many
folks pay $1200 per seat for Sun Studio out of their own pocket or project budget?
If it's someone else's pot of money I can see getting the support as a hedge or maybe
one copy out of 20 I might get support for on a mid-sized project. I don't see dropping
$24K to get 20 seats though like we used to have to do.
And its not copylefted nor, as far as I rememeber, open sourced but Sun's effective
sale price for that piece of software is now zero.
