I am working for many years in the publishing business (dealing with structured documents, product data etc.). I can tell you, that all of my customers are more open XML than any other document formats (there exist none as suitable for the job).

You can call me clueless or dishonest, I don't care. I can only share my experience with the topic. You don't have to believe me.

Your customers in the field you work in, perhaps, but it's hard to tell that's what you mean when you write data exchange. It's a wide field that is not limited to the publishing business or your customers.
