Personally I don't care that much if something is open or closed as long as it works as expected. Jolla wants to be a comercially successful company so they can't rely on thousand different opinions, whishes and desires on how things should look and work. That just wouldn't work.
So if the tipical lifespan of a device is 2 years then the company should properly support it for those 2 years and not put "won't fix" next to the multiple times reported bug. Or if some feature is missing then the company should implement that in its own (open or closed) already existing program. I don't see the point in that some community members spend weeks or months in recreating music player just to add equilizer if the company can do that much faster.
There should be an open and honest communication channel between community and company, a place where we can ask a question and get an answer on why something can or can't happen.

But I do agree that a device should belong to the user as much as possible.
