The Cybersecurity Information Sharing Act (CISA) memes focus on the controversial 2015 US law designed to facilitate the sharing of internet traffic information between the government and technology companies. The meme culture surrounding CISA typically centers on the irony of the bill's name, portraying it as a euphemism for state-sponsored surveillance and the erosion of digital anonymity. These memes often feature classic formats to mock the idea that 'sharing' is voluntary or beneficial for the average user, serving as a form of digital protest and cynical commentary on the relationship between big tech, legislative power, and individual privacy rights.
