I have met many, many people who gladly pay for Office (specifically, Excel) or Visual Studio, so much does it increase their productivity. I'm not one of them, but I'm not an accountant and the code bases I work with are small and don't require VS's incredible tooling.
There are also adherents of the cult of Visio, but I honestly can't fathom what they see in it.
Microsoft can be faulted for many things, but the reason it is so successful is that it made some really good products that still haven't been surpassed.
