Timbaland "stealing" beats?

Well, this is something that I've been seeing dicussed on various other forums, and, since it wasn't here yet, I figured I'd post it. See what the opinions on it here are.
Pretty much Timbaland is being accused of stealing beats.
For those of you who don't know who Timbaland is, here's a Wikipedia link; http://en.wikipedia.org/wiki/Timbaland
He's played a role in a lot of hits as of late. Justin Timberlake's "SexyBack" and "My Love". Also Nelly Furtado "Promiscuous", "Maneater", and "Say It Right".
Here's the quick version of the story, including sound comparsion, so that you can decide for yourself; http://timbalandtempest.ytmnd.com/ (Don't worry, it's nothing offensive.)
Here's another link that goes into much more detail; http://www.c64audio.com/timbaland.php
As for my opinion on this, I'm not entirely sure. It's sad that he sampled Tempest so heavily, and didn't give him credit. But, that doesn't make any of his 'work' any less anything. As I said, not sure yet.
