Being on the defenders side, I would say it is not a losing battle.

It is a matter if convenience versus security: not using up to date libraries because it requires some code rewrites and “aint nobody got time for that”, adding too much logic to functions and scooe creep instead of segregating services, not microsegmenting workloads, using service accounts with full privileges because figuring out what you actually need takes too much time; and the list could go on.

I am not blaming all developers and engineering managers for this because they might not know about all the intricacies of building secure services - part of the blame is on the ops and security people who don’t understand them either and think they’re secure when they are not. Amd those folks should know better.

And third, hubris: we have all the security solutions that are trendy now, we’re safe. Do they actually work? No one knows.
