 From section 0:

“The Program” refers to any copyrightable work licensed under this 
License. Each licensee is addressed as “you”. “Licensees” and 
“recipients” may be individuals or organizations.
...
A “covered work” means either the unmodified Program or a work based on 
the Program.


I suppose one reading of the definitions might agree with you. I would 
argue that the above definitions suggest that the terms "The Program" 
and "covered work" are mutually inclusive and hence don't have much 
difference in meaning.

I suppose you might be right in intent though. It certainly sucks for 
people working with interactive but limited user interfaces because the 
GPL v3 appears to prevent use of code in those environments.

Best Wishes,
