Indeed, because nothing is ever free. The cost is simply paid by someone else. Listen, I understand why that ideology is appealing, particularly if you haven't seen it play out before. How many "successful" open source projects have you seen whinge and struggle and eventually be abandoned and collapse, due to their lack of sustainability? All the while scrambling to offer the most permissive license possible? Even projects that shoulder entire ecosystems! It's better when the costs and assumptions are above board: better for the project, better for the users. I'm not familiar with the MINIX project, they've clearly found a way to stay sustainable if they've been around for 17 years. Just that paragraph quoted by OP struck me as very odd as well. Just pay your dues rather than see your favourite project die. Businesses understand this. "From each according to his ability, to each according to his needs" offers some initial thrill but is not long-term sustainable.
