Just my 2 cents. I'm not knowledgeable in the issue, but I think we are lacking something here.

- It's not "poisoning the well". Since it's closed, we can't say for sure how strategical the closed source code really is - maybe it's STILL used in some level in other or future devices, since lot of what they do could be re-usable in some way;

- there's no social obligation on releasing a single bit of the code. They made it, it's theirs, they have all the right to delete it forever. And the N900 is well beyond it's live cycle, so no obligation here, either. I can understand the need for it, to keep Maemo itself alive, but the N900 argument doesn't really cut it alone. And MeeGo OS code is there to cover for a linux-based mobile OS.

- mobile technolgy, as far I know, involves a LOT of cross-licensing. Several parts of those pkgs must have tech licensed from another companies in some level. maybe Nokia doesn't even know how much of the code is really "compromised" by it, and will not spend the resources to comb through it and submit to legal for check afterwards.

- Whatever is closed now, is really that important, unreplaceable or isn't becoming open in a way or another through MeeGo?
