When I listen to security people rant, I can see their points and it's a bit of fun, I like a good rant. But I get the impression that they're continuously discovering new and exciting ways that individual facets of individual pieces of software (and the processes around them) suck. All without ever accepting that the entirety of the software ecosystem sucks (and that they're rarely moving the needle on that front).
All software and the internet combined is a giant ball of mud that just grows and grows as more people add onto it. There's no architecture more than the strict minimum to keep the whole thing from falling apart the moment someone breaths too heavily near it. And that's not even including when commercial interests keep trying to design their chunks of the mudball in unique ways that make themselves more money at the cost of everyone else's chunk getting more complex.
Like everyone else adding mud, security wants to get in, hit their requirements, and get out. I just don't like the chip on their shoulder that nobody else is doing enough to fix the system throughout in a way that helps them achieve their goals with the least fuss.
