Nice list where the author is trying to make a comprehensive list, but then I also have some criticism of the article. It lacks some models, and it makes an implied relationship between for-profit and non-profit. In the English language, this is commonly refereed as making money vs raising money. A charity or non-profit (say Wikipedia) is commonly not talking about making money.

Some projects is funded by an indirect sponsorship model. Best example here is google and their model of giving 20 percent of an employees time to do what ever project that the employee wants. While Khan academy model is direct funding, projects that are an result of the google employee free time model is indirectly funded project.

Then we have non-profit and what they will consider to spend money and man hours on. Sometimes, that not even remotely related to their primary purpose, but is just something that interest the people in the organization.
