That video was from Microsoft's _internal_ company-wide meeting held annually to rally their staff, so your assertion is invalid.
Moreover, it's a bad example to begin with; Ballmer was and still is absolutely correct. What makes the FOSS software ecosystem so successful? That's right: developers, developers, developers. Somebody has to write all that code and it isn't going to be the end-users. When developers get pissed off at a platform, they abandon or fork it, which is why it makes sense to keep developers happy.
Those of us who were around in the '80s-'90s remember that Microsoft's rise to dominance was partly powered by the fact that they offered relatively cheap and good compilers and dev tools and solid documentation to make it easy to develop software for their platform. Contrast that with the workstation vendors back then that charged much more than MS did just to get a compiler.
