> Enterprises have been failed time and time again by poor MS products, but techies will steadfastly refuse to move off it, so the business has no option.

My suspicion is that lots of the companies are so attached to all the MS stuff (and that's what their staff know), that it would be an incredibly large lift for them to move off it.

Like, I'm at a very windows/azure focused shop now (for the first time in my career), and literally everything is already on MS, or moving towards MS.

There are some good reasons for that, and some bad reasons, but I suspect that most of the sales process happens at the executive level, rather than the technical level (and Excel runs the world, so why not let MS do everything else?).
