> Main reason for existence of lot of file formats is that enterprises don't want just about everyone access their files and modifying them. It greatly reduces the usage of their proprietary software hence their revenues.

I'm sure this does happen, but it seems more like MBA-paranoia than a legitimate concern. For instance I sincerely doubt Adobe has lost any revenue by using SQLite with lightroom, despite various open source tools being able to interact with their lrcat (sqlite) files.
