Even if only one section of your application satisfies one of these criteria, you are not authorized to ship GPL Ghostscript or GPL MuPDF with your application unless your application, including all of its source code, is licensed to the public under the GNU GPL.

People have all sorts of opinions about what GPL means, but that quoted
section above seems pretty clear.
When in doubt about a particular usage, it may be best to contact the
vendor directly for guidance.
No one else can describe a creator's intentions better than the creator. :)

As a long-time Mac user I did too, for many years.
But the more I got interested in servers, the more I found myself
actually enjoying the command line.
Now I've been adding command line interfaces to some of my GUI apps to
allow uses to automate some operations. Kinda fun once you get the hang
I found this site tremendously helpful for learning CLI:

LOL - yes, it does.
