I agree, yes public shaming is free but he also just told the world he blew up a production database. That said I'll paraphrase Tom Watson when an employee of his made a $100,000 mistake "Are you kidding? We just spent $100,000 on your training".
He also told the world that Miso doesn't have great engineering practices. Deleting a few thousand rows is easy if you forget a "from" clause in your sql statement. Would you consider working at Miso if you knew about their poor moral standards and bad engineering practices?
I feel like more people should be publicly shaming companies so that companies realize they can't pull shit without consequences. I bet you there's a whole list of companies that fire people right before they're eligible for pension benefits, and there's little employees can do.
Docking wages for employee mistakes unless (and perhaps even if) wilfully negligent is /highly illegal/ in every state in the US, and will have the Labor Board all over your company and slapping you hard with fines and punishment.
