The way to make money with Open Source is to incorporate it into products, which is why hardware makers are indeed a driving force behind Open Source development. True "Open Source companies" generally sell their services and development resources to such hardware makers. Such as mine and quite a few others who develop software for Nokia, in addition to their internal software teams. It is a common mistake to believe, that software companies are legit only if they make their money from selling or otherwise monetizing software. The bottom line is, people and companies make money from Open Source software.
