Hard to believe, that perhaps MS is really seeing the light and working positively with the open source and open standards community by releasing a plug in for Firefox that allows people to read ooxml based documents.
If this story is anything to go by, it is a big move in the right direction. Alas, the MS’ untrusted reputation continues to precede it and we will have to wait and see if this really works.
UPDATE: The MS PR spin has the word “Brussels” in it. A need to appease the EU?
