Here's another big difference from the current auto industry: "Customers can also bring their vehicles in at any time for hardware and software upgrades, or they can choose to melt their vehicle down and, for instance, add a seat. Because Local Motors uses a distributed manufacturing system to make only what is purchased, it doesn't stock inventory. Anyone can come into a Local Motors microfactory, use its design lab, and work on a vehicle project free of charge."
It's tough to get more than a general sense of how much money gets contributed to which foundations by which companies – however, the numbers aren't large by the standards of the big contributors. The average annual revenue for the open-source organizations considered in the analysis was $4.36 million, and that number was skewed by the $27 million taken in by the Wikimedia Foundation (whose interests range far beyond OSS development) and the $17 million posted by Linux Foundation.
