Is there a reason that free evaluation versions of the Ubuntu distribution are not being offered?

Because, Evgeny, my employer does not use IRIS, not do they employ any kind of cloud based solution. I need an Ubuntu evaluation version so that I can code locally on my own private server before pushing to the production servers.

I was under the impression that I would need at least a license or two to use the full version for development, whereas the evaluation version let's me use single user mode for free
