It also isn’t the amount of data but the value.

On the value spectrum (high to low): - Equifax - very little but very high value data - Google - Search, Gmail, location, browsing, apps and time spent on them - Facebook/Twitter - my posts from high school and photos of me trying to look cool

Interestingly, I think Reddit could build a much scarier profile on me based on what I read and what I upvote.
