Elon Musk, the C.E.O. of Tesla, opened up all of his patents. “Tesla will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology,” he wrote in a blog post. Tesla’s competitors can now freely take advantage of its batteries, chargers, or sunroofs.
Musk isn’t entirely an altruist. Tesla makes electric cars, and will only succeed if the entire electric-vehicle industry succeeds.
