Did you read the article? He explicitly stated that the NERC standards, if implemented, wouldn't have prevented the issues.
Corporations, corporations, corporations...... it really gets old hearing people blather on like this. Large, bureaucratic organizations, whether private monopolies, private companies, corporations, and yes, governments all have similar issues.
He cites in the article that these events all had precedents, but attempts to change the NERC rules were ignored/halted in the early 2010s.
Turns out that when you are a biased person who just reads the first few sentences and rejects the article due to the ensuing cognitive dissonance, you miss things.
