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.
I just deleted my google account. Bye YouTube comments.
I wish I could just delete it. I'm still figuring out things with nextcloud and I run a youtube channel so I can't do that yet.
You could create an Odysee channel perhaps, and try to migrate there. Then you're supporting competition.
Wish I could do that too but my email is still tied to some accounts where I can't change it
