If you hop on YouTube or scroll through Amazon nowadays, you can tell how reliant Big Tech companies are on advertising. After all, [almost $500 billion](https://www.dentsu.com/news-releases/ad-spend-growth-tracks-ahead-of-the-economy) was spent on online advertising in 2024 alone. This figure demonstrates the extent to which these companies depend on targeted ads to increase profit margins, often at the expense of privacy and security.
