I used to pay for GSuite and still found my content being mined. With all due respect to Google, I find it hard to believe that they're as consistent as they believe with filtering paid vs free accounts across the service. I could be, and am open to being, wrong, though. I'm not Google. Just found myself with substantially less targeted advertising once I left. And actually that's slightly interesting - how does one…
> found my content being mined How?
I'm pretty careful about what I share with various services. Facebook (Instagram, etc) are all silo'd off to separate access points, phone is devoid of any of them, you get the gist. The only thing I didn't mind was Google, since I was paying for it, and it's easy to think that paying for it means it'll work how you expect it to and your privacy is intact.
Thus I'd keep Google apps signed in to the account, and I'd keep a tab open with Gmail all day, so short of incognito tabs, I was almost always signed into it.
Your _email_ isn't scanned, but Google doesn't even do that for free email accounts since..., what, 2014? Most people who decry the whole Gmail reading emails angle don't seem to understand this. They still track you as you move around for advertising purposes, though, and that was enough to make me just not want a Google account.
Siloing social media probably reduced my targeted advertising by 20%, and the absolute biggest reduction I found in my life was by getting rid of Google. It's honestly jaw dropping how much tailored content you get shoved at you that "waking up" from it can blow your mind (read: less depression, fomo, and so on, which more people seem to be catching on to).
YMMV though. I don't hate advertising and think it certainly has a place in society, and some people find it useful/fine/acceptable. Just noting my experiences.
