Also, AFAIR Bill Gates personally and in person intervened and paid a visit to Munich's mayor Christian Ude.
Here is an interview with Christian Ude in which he mentiones that Bill Gates was unable to understand how reying on Microsoft products would make a city "dependent":
> Funnily enough, during the conversation, he kept making new financial offers, including what Microsoft would add to the price, for the school department, for example. They continually became cheaper by a million, another million, another million, and later a dozen million. That's how important the symbol of the renegade state capital of Munich, internationally perceived as an IT stronghold, was to Microsoft.
This was Ballmer though, not gates. Maybe Gates had a separate visit.
