In the 1990s it may well have helped contribute to an attitude where nobody stopped to think whether business practices are anti-competitive.

It also contributed to some really horrible software. At one point in the early 2000s I was meeting with Windows architects about one highly-vulnerable part of IE that was causing all kinds of security grief, and the challenges of rewriting it because its API was badly crafted. Somebody explained it like this: "You've got to understand the history. We took a lot of short cuts because we wrote it during a war."
