Imagine a business person saying, "Oh, programmers protect their work by making it needlessly complex. Every few years they invent new tools and insist that the old ones are broken, so that they can re-implement the same features over and over. Today they say it's vitally important to switch to the new thing, jquery or docker or react or whatever it is this month, and five years from now they'll say it's just as important to get rid of it. That's how they make sure they'll always have a job."
That's the mirror image of what you're saying. Perhaps some of those "layers and layers" really are useless but most of them are probably to satisfy auditors or something similarly opaque.
