Don't let perfect be the the enemy of good. I fully agree with you on what the bare minimum should be, but the reality is that our definition of bare minimum is currently a fantasy. Any steps taken toward our vision is good and should be applauded IMHO. Especially when it's a major player like Bose that hopefully sets a positive precedent and gets other manufacturers to realize this is not only possible but leads to applause and hopefully more sales.

Evolution v. Revolution. I'd prefer the latter, but realistically the former is the more likely to succeed short of people like us getting control of regulatory bodies and forcing it.

what more do you actually need?

Unless you want to actually develop ON the device (and build binaries etc...), this completely allows you to use the device and connect it to whatever, so I don't know what more we should expect.

No one else is doing this, so yeay applause

Open sourcing the server code would make getting your own instance of it way easier, and maybe opening the app code so people should change the controls?
