Yes, nothing in the permissive open source license prevents a manufacturer from recovering their costs or make a profit from producing the AAU Pandemic Ventilator. Because the design is openly available and we will help anyone who makes a credible and serious attempt to produce it, we expect this to be self-regulating. We hope that if a manufacturer charges an excessive price for the ventilator this will encourage others to produce it at a lower price. We also have a strong opinion that the AAU Pandemic Ventilator should be made available at a price that reflects its simple and relatively inexpensive construction, and we reserve the right to prioritize our help to those manufacturers that uphold these principles.
