I’m defending the four years of good behavior, not the bad behavior back then. People and companies make mistakes and bad decisions, and I don’t mind supporting them if they prove over time that they’ve changed. Four years of good behavior is long enough for me. If your response to a company doing something you don’t like is an eternal blacklist, even years after they respond to their customers and change their behavior, think about what you’re really encouraging. For one thing, never admitting anything, for another, coverups.
