Re: "The final commands were uploaded on September 29 – and now there is no going back"
Except that it was reported before they even got to the comet that the mission was Rosetta, and Philae was an added extra - if it woke up it was a bonus, if it made contact with the comet, that was a bonus, if it stuck, a bonus, if it did any of the science another bonus.
Okay, so the harpoons didn't launch and the cold-gas thruster didn't work either. After 10 years in space and ending up in a non-optimal location and attitude they STILL managed to do a whole bunch of bonus science thanks to the stuff that DID work on the lander.
If that's a failure, then I look forward to them continuing to similarly fail so spectacularly on future probe missions!
