In the article it writes "all whilst operating as an independent non-profit organisation releasing open source software.".
But this is right before talking about generating $5,000,000 in customer revenue and giving away 0% of the business.
So when you're a non-profit, what happens with that $5,000,000 of business generated revenue? How much of a salary do you give yourself? Can you even give yourself a salary if you label yourself as a non-profit? What makes paying yourself a salary as a non-profit different than a regular business?
Whenever I read sentences like that, it makes me very suspicious. Whenever I see a Ghost blog post talking about the product it always feels like they try to bring maximum attention to being a non-profit in a way that is supposed to be less evil than a profitable business but then you talk about millions of dollars of "business revenue" and I never understood how it works.
