Hi Dan,
My name is Igor, it's a pleasure for me to help others and I'll do all my best to help you.
I have to note, the user (not administrator) cannot change the ownership of other users' files, so he has to ask for (or switch to) administrator's permission. So, the message is correct. Many computers are used in a corporate environment, so users just cannot take ownership. In such cases the suggestion to take the ownership will sound as mockery. That's why the current terminology is used.
Moreover, more than 80% of program code is the same for client Windows versions and for Windows server, so server users may perceive the message as mockery too.
However, you may send your suggestion to Microsoft via Feedback Hub in Start menu.
