You're extrapolating from 1 minor typo in a presentation. If I were to judge you based on just this comment, my impression about you would be far worse than your opinion about their code base quality :)
On a more serious note, Microsoft is one of the biggest software companies. It also consistently delivers high quality products to its customers. Products of incredible complexity such as Windows, Office or .NET. They couldn't do that without good engineering practices.
And specifically in this case, the Visual Studio Code team wouldn't be able to deliver very complex features so often if their code quality and overall engineering wasn't solid.
Have you ever read any of their release notes? Have you noticed the frequency of their releases?

Those alone should make you ponder for a while ;)
