If we look at http://neo900.org/ we can see no mention of the project entering any permanent freeze(end) status. The only notification we have is at TMO. In any case we can believe Joerg and sympathise with his health and resulting financial problems, but the zombie website still has a donate-now button with unknown functionality. If Joerg hasn't updated or deleted the website I have every doubt he would try to collect from the sponsor account. The last post on the Neo900 site's news feed in 2018 leaves only hope for the continuation of the project, "Thanks for helping keep our project alive PIA! PIA would also like to thank Neo900 supporters for staying strong with the project so long"
(edit)I did poke around the website a bit, and while there are buttons to donate or prepay for a Neo900 there is not any buy-able objects available in the store. I would consider leaving such site up myself were I former lead of such an agressive project as a living CV and proof of great small team accomplishments to show prospective employers.

GDC was behind the OpenMoko a phone which while never terribly functional as a phone was pretty cool as the first(AFAIK) phone designed bottom-up for a FOSS OS and userspace. I have a GTA-02 which still works and I am thankful to Joerg and associates for the work he did on the moko series as well as some sweet tweaks and feature hacks toward improving the N900 experience(USB hostmode and H-E-N especially) not to mention his regular presence on TMO.

But appreciation of our friends and allies aside the presence in the top device slot of talk.maemo.org for the Neo900 project, one which is no longer a project with any realistic hope of reaching production, and even if someone else obtained the Gerber files it would be a 10 year old design with long EOLed components thet even GDC had to scramble to obtain.

I know that there are some useful side and on-topic discussions in the Neo900 threads which we need to keep web-searchable into the future. I mean no disrespect but stacking Neo900 at the top of Maemo devices discussion is misleading to newcomers and is a space possibly better suited to discussing the future of Maemo devices, maybe those compatible with a Maemo-Leste port.

I restate my support for moving the Neo900 topic to Old and placing a prominent sticky at the top of that subforum(perhaps also some version of 'never entered production' note next to the TMO main link) respectfully explaining with quotes from Joerg that the project has reached it's end without producing a production ready device and that announcement's date.

(edit)The pessimism is warranted, the project is announced dead by joerg_rw there is nothing to be optomistic about at this point, I have no grudge with Joerg, rather I appreciate his work and use USBmode on my N900 frequently with thoughts of thanks to him as well as the other good he has done for us in the past on this forum. But in the real world the Neo900 project is dead with no devices in the wild, there is no reason for a Maemo tech discussion forum to, after the end of a cool nearly realized dream, to project an ultimately unfulfilled fantasy as factual.
