One of the issues I take with this mentality is that companies are always looking for excuses to sell bad software. As an engineer, I really don't enjoy maintaining crappy SaaS, particularly if they are built with weakly typed, dynamic languages. If something is obviously prone to fail you should empower people to do something about it, because usually "letting it fail" will lead to your users switching to your competitor's offering.
