I am really tired of the people like you who say "you hate them just because they are Microsoft". I'm tired of having to explain this. I wish you would do your homework before you make such accusations.
I don't trust Microsoft's intentions because of their past business behavior. That is the basis behind every reason I have to not want to support Microsoft technology. If you want to know some examples of bad Microsoft business activity, go use Google. There is tons of information out there. Just PLEASE stop acting like people that don't support Microsoft technology are just jumping on some bandwagon. I'm sure some people jump on that bandwagon blindly (they are human after all), but MANY people actually don't want to support Microsoft technology for good reasons.
Even if you like Microsoft, there are many reasons why not to support this format.
Microsoft certainly could embrace and be involved with the Open Document format, but they choose not to. Creating their own standard which is largely based upon their existing proprietary formats will keep inline with their business model. Simply put, they want to control the standards.
Many people have complained about how poorly their standard is written, where some portions of it are described as "do this part just like MS Word does" and other vague nonsense. Some of the spec is designed around old Microsoft bugs, inconsistent naming conventions of properties (a carryover from MS formats), and the list goes on. There is even use of the name "Microsoft" in some of the namespaces.

Look at this part in particular

Specifications that say "clone this product," instead of explicitly stating what behavior is required, have no place in an international standard.
Contrary to what some people claim, Microsoft does make (some) good software. Much of it could be improved, but some of it is done pretty well (for example, Exchange server). But their software stands upon a business model that I absolutely do not trust.
