> Now, I'm not asking companies to open-source their entire codebase. That's unrealistic when an app is tied to a larger platform. What I am asking for: publish a basic GitHub repo with the hardware specs and connection protocols. Let the community build their own apps on top of it.

The actual proposal in this blog doesn’t make much sense. Having the specs of a device isn’t going to change much because they can be determined by anyone examining the PCB. Most devices don’t have a simple connection protocol, like the Spotify Car Thing used as an example.
