Sorry I should have phrased that as starting in 1990...

In 1990 they poached Brad Silverberg who then spent the next 7 years poaching all of Borland's top talent in the most prominent example of a competitive 'brain drain' strategy that I'm aware of.

Fair point!

>Anders Hejlsberg didn't move to MS until 1996...

The point of the comment wasn't the specific date, it was the impact of hiring a competitor's team AND equipping that team to be even more impactful.
