i was talking to some guy (who and where is unimportant) and he mentioned something that got my attention...
he was saying something like he wonders why ms doesn't sue openoffice for use of their formats. he was comparing it to adobe protecting its *.pdf format.
it got me thinking. first of all, who would they sue? thousands of developers who are unnamed? but that is besides the point.
is it because MS can't copyright/patent file formats or something?
