I created a google takeout and in that zip file I found some files containing a ton of data about me. It has logged every single page I visited while using the google search engine and chrome browser. It even logged every single time I opened an app on my old android phone. It even has VOICE RECORDINGS of me and a log of every time I used google assistant. This is just some of the data and I’m very sure there is even more data they have.
Also for a good read on Google and Meta, check out Jedi Blue. It’s a plan that FB and Google got sued for, for manipulating ad auction timings in favor of FB on Google in exchange for FB to promise to not open a competing ad service plans. They also gave FB access to every google device with Facebook (preinstalled esp) on it. The name Jedi Blue is a reference to the Jedi mind trick, assholes.
