Where are they going?

I’m human, so I’m built to notice patterns.
Here’s one I’ve noticed on some products/technologies that either I or people I’m close to use and respect.
MySQL founder quits Sun (Sep 4 2008)
Stewart Butterfield’s bizarre resignation letter to Yahoo (Jun 17 2008)
Delicious founder leaves Yahoo (June 19, 2008)
Microsoft ‘Halo’ creators to be separate company (Oct 5, 2007)
It doesn’t necessarily mean these things are dead or have no future, but it doesn’t make me feel warm and fuzzy either.
