I am just claiming that the value is described in the GPL: the currency to use is "source code", and the amount is "all derived work and way to reproduce".
If you want to pay in another currency like hard cash or reputation, GPL is not the license to use and you would better ask the copyright owner for another license (he/they may acccept cash as currency).
The copyright owner may very well have put his source code on the net under GPL to be able to see if someone can make money out of it (like building a TV) and wait himself for a part of this money because the GPL is unworkable to produce a TV.
That is a buisness model I would not object to - the only thing I know about GPL software is what the GPL says (and I have spent time reading it).
If you build a TV, you can ask the copyright owner to use his source code in exchange of increase of reputation like telling everybody that this guy is a genious on all TV channels - that would be another valid license.
If you refuse to accept the GPL terms and refuse to negociate anything else, and still use the source code - I just claim that is stealing (because the copyright owner work has some intrinsic value that you refuse to "pay for").
