I think a small issue with foss and monetization is that you can accept money for said software hell even release it with expectations that you have to pay for it, but you can't insert a clause in the license that stipulates that the foss rights only applies to paying or paid customers. Thus there is no legal protection you really got if you go foss as a developer when it comes to ensuring fair compensation.
