The concept of privacy has evolved over time and is not fixed; it's been shaped by technological advancements, societal attitudes, and legal frameworks. The rise of social media platforms like Facebook and Google has led to a shift towards real identities, but this has also sparked controversy and criticism about data collection practices. In recent years, there has been a growing focus on privacy as a business model, with companies offering private actions such as secure email services and anonymous messaging apps. However, the pendulum of privacy swings both ways for products, and users are increasingly making judgements on which side of the line they fall on. The popularity of anonymity and ephemeral messaging apps has also highlighted the importance of flexibility in online interactions, rather than just privacy. Ultimately, technology is playing catch-up with what society deems correct when it comes to privacy, and it's a complex issue that continues to evolve.
