Does the breach call for some punitive response? Definitely. Does it justify destroying a $14B company? No. That's an overly emotional, witch-hunting type of response.
HN of all places should be sympathetic to what happened to Equifax; they neglected to update a framework which had a vulnerability granting full remote code execution. That's game over from an info sec standpoint, and how many developers here can state, with 100% confidence, that every library and every framework and piece of application code in their own work is totally bulletproof and will never fall victim to something similar?
The breach should be used by everyone as a lesson, and as I stated earlier Equifax should receive some punitive action (arguably already delivered by the hit to their stock price and the public floggings from the congressional hearings). But saying that Equifax should be bankrupted by it, or that the executives or developers should be thrown in jail? Be careful what you wish for. Today Equifax, tomorrow you.
