Seems like all this flaming nonsense has blown through, I hope. So, now for some proper discussion.

What pressure can be exerted, by who and on whom, in order to fix those functions which do not perform as advertised/reasonably_expected*.

The release could be by PR (or equiv.) (unlikely) or code, which would require an amount of effort to. Are there any cases where the interface (inc. comments) would suffice and where the release of the implementation isn't required?

In addition to any code that might be released, documents and code-comments are much needed.

Instead of a yes/no poll, a top 10/top 20 list of fixes. BME and dialer are mentioned, for me it's vsync and video frame-drops that gripe. In many ways, I don't mind that much about all the code but I mind a lot when the device doesn't do what it says on the tin or features have been unreasonably turned off (e.g. input devices) and yet, I'm obliged to pay for it all the same.
