Utter incompetence. Developers seem to have this almost-magical ability to blame management for their fuck-ups. Guess I can't blame them too much, there's practically no decent software engineering training anymore. All we get is irrelevant science-y shit.

> We came up with a plan that would eliminate the risk,

You don't call it a risk if there's a 100% chance. Managers are not going to understand scenarios you put in front of them, you have to guide the conversation. You say, "this is going to happen if we don't fix this right effing now." Then you threaten to quit if they don't take you seriously. But again, professional pride is something nobody teaches developers.
