If I recall correctly, each of these were initially developed as
proprietary products that were later released as open source. ROI
recovery was accomplished during the proprietary phase.

This is not a bad model, but it isn't a purely open source model. I
would be reluctant to start a business on the premise that the code
would later be released. Acting on that premise is too subject to the
whims of investors and board members.
