The realty is that donation-based is not a sustainable business model. You basically can't always afford to eat based on it, leave alone to rent an apartment.
Ditto for the much touted GPL “service model” - charging for support and training. Realistically, this just does NOT work for anyone except for RedHat, because otherwise there would’ve been plentful examples everytime this subject surfaces and there’s always none. Also saying this as an ISV with tens of years of experience - making living off GPL-licensed software through secondary services is an absolute suicidal pipe dream. Even the double-licensed model (which is not applicable in Belnder's add-on case) is dramatically inferior to more conventional licensing models.
