As usual, I got an e-mail from my NAS-box stating, that it has a new firmware upgrade QTS 4.3.3.0404 build 20171213.
It had the usual release notes telling the changes. What really caught my attention was:
QTS 4.3.3 is the final available firmware update for the following models: TS-419U II
WHAAT! Just out of the blue, my model was obsoleted piece of junk! 
The actual full list of models is: TS-112P, TS-212P, TS-212-E, HS-210, TS-112, TS-212, TS-121, TS-221, TS-421 TS-120, TS-220, TS-420, TS-420U, TS-421U TS-412, TS-412U, TS-419U, TS-419U+, TS-419U II, TS-119P II, TS-219P II, TS-419P II, TS-119P+, TS-219P+, TS-419P+, TS-119P, TS-219P, TS-419P, TS-119, TS-219, TS-419
So, only the recent QNAP boxes were maintained from this point on. Darn! My take on their decision to stop maintaining all the old models is, that initially they barely maintained them at all. In fact, QNAP got burned seriously on not acting: 0-day: QNAP NAS Devices suffer of heap overflow. In less than two years they managed to get that one fixed. They received information on 1st Feb 2016, but fumbled on the fix until 14th Feb 2017.
To me that action (read: lack of it) means, that they did not have a protocol in place for a situation where a security flaw would be found in one of (read: all of) their main products sold to general public. While spewing out unfounded allegations here, I'm pretty confident, that it wouldn't have made any difference if the security flaw was in their internal systems.
Now that they chose to create processes, assign personnel to it and start maintaining their products, they suddenly realized, that IT'S HARD WORK! 
Oh really! Rest of the world knows it already. But that's what you need to do when you are in device manufacturing business.
Ok, enough rant. Now I have a decision to make. What to do with a perfectly good NAS-box. Suggestions are welcome.
