Well, I'll play Devil's Advocate again...
The point of "No Tech Brokering" is that you can't trade techs you didn't research. In fact, the mouse-over help for NTB says just that - "Players cannot trade technologies that they have not researched themselves". Since you didn't research the tech you stole, wouldn't that mean you shouldn't be able to trade it?

No Tech Brokering means only the discoverer of the tech can trade it. Leave it that way.
I'm not sure what you mean by "leave it that way". Currently, you can trade techs that you've stolen with No Tech Brokering on.

AI now knows how to use Steal Tech and Incite Revolt
AI's may choose to concentrate on large espionage missions (like steal tech and sabotage project)
Increased likelihood of the AI stealing techs
You could make up a reason like: 'the one who taught you the technology don't wants you to trade it", but that can easily be countered by: "what do I care what they want after I've acquired the technology". So as I find the tech brokering option an unrealistic playing option, I will stop trying to use realism arguments to decide whether stolen technologies should or should not be available for trade.
But there are many other similar situations in the game. For example, peace treaties means you can't declare war until 10 turns have passed, no matter what. But what's ACTUALLY stopping you? Nothing. So, unrealistic as it may be, these sort of artificial restrictions exist to prevent various "cheesy" tactics, even though said chessy tactics would be used in a real life situation. But this is a game, and some measures must be taken for the sake of, for lack of a better word, balance.
So the same way peace treaties enforce an unbreakable peace, no tech brokering enforces an unbreakable end-user agreement for traded techs, forbidding re-trade.
But stolen techs, now, are of course not the same. But as it is, it represents a workaround. Set no tech brokering and divert some points from spying to research and you CAN trade techs that you wouldn't have been able to trade with if you had aquired them by trading tech for tech. Instead you trade spypoints for tech.
The clincing argument for me however is that being able to trade away stolen techs udner a no tech brokering game benefits the player first and foremost. For these reasons I voted no.
The tech brokering was introduced to reduce tech trading to a lower level where you couldn't acquire technologies from a foreign civilisations and then trade them on to other civilisations. The espionage mechanism now allows you to avoid this restriction. I therefore think trading stolen technologies would be against the basic idea of the tech brokering option.
