MacOS is also an operating system or a platform. Tesla isn't really a platform.
But... funny you brought up Tesla, because Tesla also had this exact problem! Tesla had the supercharging network, which they own and manufacture. But superchargers aren't just a product, they're a platform.
Tesla had a monopoly on superchargers, until they pre-emptively opened up the network and open sourced the connector. If they hadn't, IMO it was extremely likely they would've been forced, eventually.
