I politely disagree. Finding the Core ISO is harder than the Server/Desktop ones. https://ubuntu.com/download/core
There’s a Build Your Core button. And that takes you to a docs page that lets you download a pre-built image. I think it’s pretty obvious that this is not the Desktop Ubuntu.
The money comes from corporate customers, that’s the sad truth. If you go to RedHat’s website, their Worsktation option is hidden in menus as well. Fedora doesn’t seem to be mentioned at all.
