- A network of 24 media extensions that are installed on 800,000 users and collected viewing data and demographic information on major streaming platforms such as Netflix, Hulu, Disney+, Amazon Prime Video, HBO, Apple TV, and others
- 12 separate ad blockers with a combined install base of over 5.5 million users openly selling user data
- Nearly 50 other extensions, with over 100,000 users in aggregate, that collected and resold users’ browsing data
