The entire purpose of Microsoft standardizing OOXML and implementing it wrongly in Office was to make other office suites irrelevant. ODF was already standardized and countries would have adopted it if MS didn’t do the same with OOXML. They stuffed the ISO with members supporting them to do it.

And now that OOXML is a viable standard, they implement it wrongly so that other office suites can’t be compatible with MS Office without a lot of extra effort. Any incompatibilities with MS Office will be considered as the fault of other office suites by the general public and government officials.

Expecting MS to do what’s right for the customers is putting too much faith in their nonexistent sense of ethics.
