Do you know of any major Linux distribution besides RHEL that charges a subscription fee? I don’t.

Edit: I poked around the site a little more. I had quite a bit of trouble sorting out what the comparison was between costs of different Linux distributions, but (a) it looks to me like the cost of Redhat is exactly the same as the cost of Ubuntu (b) it looks like there may be some sort of bundled corporate support as part of the package, for which I’m sure there’s a cost © their list of which distros to include (Redhat / SUSE / Ubuntu) is quite weird coming from the Linux world. Most providers I’m familiar with default to Debian for servers.

Regardless of that, my question was independent of a support agreement: Do you know of any major Linux distribution besides RHEL that charges a fee and requires an agreement with the manufacturer to use or download their production version?
