Kind of a shame when companies do this.
I also wonder how long till the hacker community starts hacking these things any way? Seems like a worthy device to hack, though I can't imagine there's millions of these out there. I'd love to buy a 2nd hand one and install custom software on it if someone builds said firmware.
Hell, if Spotify had open sourced this and still sold them, I might have bought a first hand one. I would just be streaming my Apple music to it instead. ;)
