Why do people tolerate MS EULA's?

There was a time when second hand software was perfectly legal. I have not used MS software for a decade, but I gather the licence just keeps getting worse. How many Vista sales are repeat sales for the same machine just to get one restriction in the license removed?

Apparently Dixons have a pile of unsold Vista licenses. It looks like someone abroad had a similar problem, and sold the licenses here - and this is not permitted by the license?

I wonder why anyone one even considers distributing properly licensed MS software. It does not sell, and if you do find a market you get sued.

When MS sued their own customers it was beyond silly. Suing their distributors does not look like a good way to grow the market to me.
