None of the above has changed with any recent announcement.

Our current best bet is to help out the CSSU team and rewrite any closed source packages (they have already made some remarkable progress)

Of course, some packages, like the dsp, may never be re-written; but typically these contain IP from third parties so not a lot Nokia can do..
Others like bme is probably owned completely by Nokia, but they'll never open them for fear of litigation (whether that is a valid argument or not is irrelevant, and it's not going to change because of this poll)

Anyway, best of luck with the poll. But it would help if you actually posted what you plan to do once you get a million signatures or whatever

A better use of time would be to start a Crowdfunder, with the proceeds to go to the CSSU developers.
