(✿╹◡╹) That is right. Only that it is not a licensed software. I mean
it is possible to imagine it is licensed, but it cannot be conveyed or
given to anybody unless licensed properly.

You got it right.

Ubuntu is operating system, is is collection of software. It is not
impossible to have collection with mix of proprietary and free
software, I have seen such collections since 1999. 

Emacs support for proprietary software would be possible if such
support is in terms of a mode that just takes care of editing.

Problem would be if Emacs package requires the proprietary software
and GPL-ed software in the same time.

The IDE and modes most probably do not require, they would just
execute external problem.

Yes, but you got it.
