I have ranted previously about the evil of Microsoft Word. One of the issues is the use of proprietary file formats that keep changing, both to force Word users to buy upgrades to be compatible and to prevent other word porcessors to manage to read or save into the Word format. It turns out at least this aspect of Word is coming to an end.
According to The Motley Fool, Microsoft has now agreed to adhere to the open-source ODF format. This will make Microsoft Office format compatible and easy to interpret. Microsoft is seeing now the consequences of its strategy, which drove ore and more institutions away from MS Office. So it seems markets can force monopolies to behave.
