> At Tesla, however, we felt compelled to create patents out of concern that the big car companies would copy our technology and then use their massive manufacturing, sales and marketing power to overwhelm Tesla. We couldn’t have been more wrong. The unfortunate reality is the opposite: electric car programs (or programs for any vehicle that doesn’t burn hydrocarbons) at the major manufacturers are small to non-existent, constituting an average of far less than 1% of their total vehicle sales.
I read this as effectively saying that it's easy for them to take this step, relative to companies in other industries (Apple, Google, Amazon, et al) because none of Tesla's competitors even have the ability to make use of their technology. Makes me wonder if Musk would have done the same thing if Tesla were a software company.
