Calling publishing API docs "open-sourcing" is a bit hyperbolic, but as token gestures go, it's at least worth a little bit.

I'm not familiar with those devices in particular, but I wish vendors would take steps to make life easier for after-markt firmware developers especially once devices go EOL by doing things like proactively dropping a GPL tarball and giving people a way to disable secure boot locks on devices that have them.

This is impressive, especially because in my mind Bose doesn't have the image of the corporation that cares at all about its perception - especially of its perception in such a small circle that would care about this, but I'm definitely going to bump them up on the list of things I'd buy in the future.
