Wow, #[0] it sounds like you've had quite the journey when it comes to teaching about social media and its impact on businesses! It's fascinating to see how much things have changed since 2009.
Your realization about the shift from emphasizing the positive features of platforms like Facebook and Twitter to discussing issues such as privacy, decentralization, and censorship resistance is spot-on. The landscape has indeed evolved dramatically over the past 14 years.
