Seeing as I seem to have triggered something there, let me clarify slightly.

1. You can(!) do without Licenses etc as you can get eg 10K copies of eg Centos (which is unsupported BUT you do get updates).

2. Alternatively, (if you want), you can pay for support & updates by getting a contract with RH.
Note, as above, you can install the 30 day free trial of RHEL on 10k boxes if you like, but you WON'T get updates or support after 30 days.
It will NOT delete itself or stop working in any way when the 30 day trial expires. The 30 day part is only(!) for updates/support.
This does include src code BTW.

Basically you need to decide if you need paid support or not ... yours or your manager's choice.

HTH

Chris quoted,

Which is clearly incorrect as Redhat has a support contract (license) which enforces the user to pay if they wish to continue with updates for their RHEL products. We all know that if you want a truly free Redhat based server or workstation then you use CentOS.

If I was a serious business user looking for this then I would not be looking at bittorrent nor googling sites for a free download - I would probably end up here, where it greets you with

No, I'm not forced to pay (at least for the first 30 days) but I basically end up with crippleware if I don't front up with the cash.

With Ubuntu, for example, I can freely download and then choose to take out a support contract at a later date. if I choose not to have a support contract then I can carry on using it without compromising my server and workstation infrastructure as I will carry on getting updates.

Right, which is what was said all along. You CAN get Red Hat free, and use it free. AGAIN, you PAY FOR UPDATES and support. Want to update it yourself manually from source packages? Go right ahead.
Nope...not crippled in any way, sorry. The ONLY thing you will lack is the paid-for support, and updates from Red Hat. That's it. What's 'crippled' about it? What server functions won't work? What services won't start? What does it prevent you from doing, except getting something that they sell, for free (which are updates and support)?

And if you ARE a serious business user, you would PAY for your servers to be updated/patched, and (since you're a 'serious' user), would know that your servers don't run in an isolated environment. If you're running Oracle on openSUSE, and you call Oracle for support...you likely won't get it, since it's not one of their supported OS'es. You pay for a supported configuration, and certification of the OS to interoperate with whatever you load on it, from Oracle to VOIP services. If you are a serious user, you would pay for it and not worry about it. If you want to use it at your own risk (like you do with ANYTHING community supported, like CentOS, Ubuntu, etc.), you're free to do that.
...which is why using CentOS instead of Red Hat is often suggested. Red Hat's product is their support/patches, which (amazingly), they charge for. Don't want to pay? Don't. Again, you can load updates to any library manually from source, which you can get from their website. Not seeing the problem here.

We seem to be going round in circles, let's agree to disagree...

No circles at all...you seem to be missing/ignoring things. Red Hat is free. Use it or don't. Have fun.
