While I can think of a few other, dotnet and Visual Studio, I think that you're generally correct.

Microsoft, Google and others, have created a culture that are no longer able to produce high quality solutions, because they can't focus on a single vision for their products. Or in some cases the vision does not align with creating good products.

SQL Server is a really good example, it's highly focused, it exists outside the current hype bobble, there's no advertising, no subscription, just a database server and it's a really good product. Exchange sucks, because it been pulled in to new subscription based world, and it's going to suffer for it.
