The Comforter?
The Bill & Melinda Gates Foundation is actively involved in buying AIDS vaccines for Africa. But the laws that govern patents and intellectual property that keep African nations from buying cheaper, generic versions of these vaccines are also the same laws that protect Microsoft's international patents on things like Windows & Office.

Alterior motives, anyone?

Greg Palast seems to think so. If you skip over all the stuff about Tony Blair on Palast's blog, you can see what he's getting at.
