I thought plagiarism was an issue of false attribution? If my product gives attribution to the original authors, but I do not release my source code, then I am in violation of the GPL, but I am not a plagiarist.

Yes, that's precisely what I've seen people get annoyed about when the issue of copyright violation comes up.

I thought the GPL allowed binary-only distribution as long as there was a link or similar in the program to somewhere the source was available, but apparently not.
"The general rule is, if you distribute binaries, you must distribute the complete corresponding source code too. The exception for the case where you received a written offer for source code is quite limited."
It's hard to violate the GPL without plagiarizing.
