and microsoft can do that, because odt is open data format. that is the whole points of open format, that microsoft and anyone else can do that and we can freely exchange data no matter what specific application we use to create them. you know what is not open data format? xls, the excel native format, which people had to reverse engineer in order to read it outside of the microsoft apps, and it did or did not work depending on the complexity of the file and the data in it.




no, it will not.
open data format is a format that has publicly available specification and anyone can use it, as opposed to formats whose specification is not publicly available, the only way to use them is to reverse engineer them, which is something their author (for example, but not only, microsoft) actively tries to prevent by constantly making undocumented changes, in an attempt to lock the users into some private software ecosystem.
purpose of open data format is that anyone can share and exchange data, no matter what apps they decide to use, so trying to prevent anyone to use it would be directly counterproductive.
so for example i use libreoffice, you use ms word, and we can exchange the data files and they look as intended on the other person’s computer, because microsoft is free to read and write odt files, their documentation is publicly available and no one asks microsoft to start giving out ms word for free or sod off.
