> Plenty of other open source projects make money without attracting this kind of negative feedback
We dont seem to be living in the same reality. In mine, maintaining open source projects is a nearly-completely thankless, profit-less endeavour. It is a rare exception that someone can earn a living from it. And datastar's devs have zero expectation that they'll do so, even with this model - hence it is registered as a 501c3, and the funds will cover things like travelling to conferences to talk about it.
