What strategic decision did Bosch make regarding the CAN specification in 1991 concerning proprietary control?

Answer

Released the specification details publicly

A significant strategic move by Robert Bosch GmbH was their decision in 1991 to release the specification details of the CAN protocol publicly, rather than keeping the technology strictly proprietary. This open approach was instrumental in driving down the cost of CAN controllers because it allowed numerous chip manufacturers to enter the market and produce compatible hardware. This widespread availability and competition encouraged rapid and broad adoption across the entire automotive industry, preventing the potential fragmentation into competing, incompatible standards that might have arisen if Bosch had maintained strict control.
