The Cambridge Analytica scandal is about campaign financing, possible law breaking and Brexit. It’s also about money in politics. It’s about the continuing irresponsibility of platforms like Facebook. It’s about the systemic problem of data exploitation and surveillance capitalism. It’s about targeted advertising, persuasion and manipulation.
It’s also about a shady company that has possibly broken data protection laws (together with political campaigns, and other data analytics firms). It’s about neo-colonialims and global inequalities. It’s also about foreign interference in elections and government propaganda (not just by Russia). It’s about GDPR and compliance - competition law and consumer protection.
In other words: this is complicated.
