Truth be told, they'll be ruined by their bean counters. They aren't unaware of what it would take. The simple fact is, they're selling heavier buffers and better springs in sufficient volume to make money after they've sold a defective product. As long as they're making money off both the problem and the fix, the bean counters will leave the spec in place. DC Machine knows what it takes to fix the platform. PSA owns and specifies the platform. PSAs decisions aren't based on the fact that they don't know, nor are the manufacturers decisions based on the fact that they don't know. DC Machine sells parts to PSA whether or no not PSA has them well specified, and therein is the issue. The blame lies completely with PSA in my book, they know the issue and how to fix the spec and have done neither based on the almighty dollar. DC Machine can't be blamed for supplying their primary customer with precisely what they're asking for, that's what any respectable machine shop would do.
