The article lists 17 of the worst offenders in online privacy invasion, including the Meta family of apps, including Facebook, Instagram, Threads, Facebook Messenger, and WhatsApp. These apps collect massive amounts of data through various apps and services, often used for product sales or targeted advertising. While platforms like Apple and Google have implemented measures to educate users about these issues, some apps are worse about collecting data. The article highlights the most egregious example of the Meta Pixel, a small image posted on many popular websites that reports back what user did on these webpages to Meta. Other notable offenders include TikTok, which has been accused of aggressively gathering user data for years and has been sold to an American company by its Chinese owners, ByteDance. However, despite these efforts, Pinterest still has faced controversy over its data collection and use of off-site activity. Amazon, which collects a significant amount of user data, has been criticized for its excessive data collection.
