Initially I'd say well if you're a public figure and upload your own voice online, of course this will happen. So its something to expect, however, this shouldn't be a problem for Jeff to solve... instead it should be YouTube's problem as they profit from the video monetization. Eventually they'll have to have some kind of detection for all uploaded content.

I strongly disagree. I don't know the rights around one's own voice, but the idea that you suddenly lose ownership of something because you shared it online is the exact thing that many people take issue with when it is written in the terms of service for social networks, creator tools (adobe), etc.

I didn't mention ownership and I don't think you should lose it (nor does one lose it really even in this case, legally). But I do think that in cases like these, where there's money involved and YouTube, that they should have the means to prevent it.

Issue is that Youtube profits off it while signing away liability. There's no incentive to prevent it.
