I think most people forget that Edsger W. Dijkstra was a computer scientist not a software engineer. He most likely wrote programs, but not build software systems. As much as I've enjoyed most of his writings and musings, one must bear in mind that they most likely apply to programs not software systems built in the large. If you are writing one little program and have one type of data, it's easy to begin with data. When you have a complex system operating on 500 different types of data, it becomes easier to encapsulate with OOP.
