It's rather that they're not distributing it (either source or binary) so the GPL doesn't apply to them. Not having access to the source doesn't exempt you from the GPL.
But they are getting an unlicensed product. IMNAL, but if they are made aware of the fact and continue to use the product, wouldn't it be willful misconduct?
If the GPL completely doesn't apply then you don't have a license to use the program.
You don’t have a license to copy the program, the gpl does not grant you a license to use the program as you do not need a license to use a program.
If you don’t agree to
The gpl normal copyright law applies and you can’t copy the program outside of fair use in your jurisdiction
If I install a pirate copy of a program on your computer, can you use it without a license?
What law would I be breaking in what jurisdiction? I’m not familiar with Somali copyright law, and that’s the main source of pirated, although I did read an increasing number in Nigeria too.
