Maybe I'm seeing what I want but it seems that the plan is for the document formats and editing programs to be free while generating revenue from infrastructure around delivering something "Sharepoint-like" (or a SaaS service to do similar), complete with a throat to choke/vendor to blame if things go sideways. I don't see this as fundamentally different from the choice of running CentOS versus paying for RHEL: the latter is the same software but comes with enterprise assurances that allow the CIO to sleep at night. I'm sure there's someone could write a compelling essay along the lines of "Free Software isn't free of charge" if someone were inclined to pursue it. Even people like RMS have to eat from time to time.
