That's rough. I've had similar experiences.
TDLR: Needful, worthy improvements require champions. A thankless role. And few of us have the resources and tenacity to serve the champion role for the long haul.
In trying to understand organizational psychology and apparent apathy, I keep thinking of Stephen Jay Gould's theory of "punctuated equilibrium" meets the attention economy.
Metaphorically, organizations (and people) are information processors. Attention is our scarcest resource. We're all doing triage, at every level. Just trying to cope with the torrent of information, discerning signal from noise. Trying to prioritize efforts.
So it's almost inevitable that needful, useful, worthy things remain neglected, undone. Even in the absence of pushback.
Until some kind of crisis. When the neglected thing suddenly becomes very important.
Cue the fire drill. Something must be done.
The champion must be watchful, ready, proactive. Seize that very brief opportunity to sneak in their needful improvement. Ahead of the all the spazs pitching their weird and wrong and ignorant reactive proposals.
The only winning strategy is to just keep pushing. Patiently, diplomatically. Be that useful thing that everyone's dimly aware of.
"Oh, wasn't Con Kolivas working on that mouse jitter thing? Ya, I heard it's pretty good. Ah, it's ready to go? Cool, let's do it."
If your needful thing is truly worthy, be confident that eventually it'll percolate to the top of the triage stack.
This game truly sucks. But I don't see how it could be any other way with our current decision making structures.
