This document discusses how large open source projects can be monetized. It begins by introducing Bruno Lowagie, the original developer of iText, and poses the question of how to monetize large open source projects. It then discusses some of the expectations and demands users and companies have of open source developers. Various monetization strategies for open source projects are presented, including donations, ads, documentation, support, and dual licensing. The document uses iText's experience as a case study, and discusses licensing options like GPL, LGPL, AGPL and open core models. It also addresses copyright enforcement and presents iText as a success story for monetizing an open source project.
