Software delivery is changing. Heavily influenced by web-based software and easy delivery mechanisms (App Store, Steam, soon-to-be-Windows App Store), we are moving into a software delivery and support system of latest and greatest only.

This is at odds with the standard operating procedure of large corporations. What Mozilla seems to be saying is that they no longer support the old way of doing things because they think the new way is better (and I agree with them).
