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.
Of all three, Google has the most skin in that game, for what it’s worth, IMHO. They’re an advertising company first and foremost, and it shows in all of their products’ feature sets and privacy policies.
But we also can’t trust either of them lol
