but surely MS want their own formats to be the dominant player, not PDF
The only way that will happen if they did a format that was as open as
PDF - i.e. viewable/editable on any platform and device (even
non-Microsoft ones). Which may be why it is Portable Document Format -
there is no portable Microsoft format (you could argue that OpenOffice
makes Word documents portable, but not entirely, and it was done
without help from Microsoft, via reverse engineering).
The fact they opened up the spec for PDF's probably helped the
dominance - if they didn't (i.e. limited to Adobe software to create
and edit documents), PDF documents would not be as popular (or may not
even exist now).
