The operative term isn't simply "survival" but "survival time", that is, the time, post-diagnosis, a patient cohort may be expected to survive on average. It is a term of art.
It's also meaningful insofar as extended survival time suggests progress against the disease mechanism. This may not mean long-term survival for present sufferers of this particular disease, but may suggest future research which is more promising, or if this route hits a wall on any additional outcomes improvements, limitations to this approach. The advance of knowledge is a benefit, regardless of ultimate patient outcomes.
(Where the trade-off in knowledge gains vs. patient outcomes lies is yet another realm of medical ethics.)
Language-lawyering the term is however specious. If you want to comment on quality of life or other matters, those are separate and meritorious discussions. You're embarking on them in a manner that's not likely to be especially conducive however.
