Speaking as one who has lived with an independent DJ for 30 years, talk.maemo.org ain't no independent record store. It's virtually run by Nokia, a major label.
But regarding the ownership: maemo.org was originally 100% Nokia, but more and more of it has been handed over to the control of the community. I don't know what the percentage is now but it's going down all the time.
Just to give an example, when I did the tablet school site in 2007 I got an email from a Nokia employee saying they'd added me to the maemo.org aggregator. When I emailed Nokia last week asking about whether our unofficial Maemo site could be added to the maemo.org aggregator, they replied that they no longer controlled the aggregator and that I'd have to go through the community channels.
