you're are right, I was a bit unclear. I guess I just feel I can trust Google more. Sure Google will take my data and deliver me targeted adverts, share it in some sort of aggregate form with partners and possibly use it to learn more about be than I know about myself, however I feel Google is good with dealing with privileged data. There data security is good and I never feel my account will be leaked, it's not Yahoo! (yet? .. that's another conservation).
It's business is fundamentally about trust, people trusting its services, I feel it offers good data security on its accounts and it offers services that I am happy I don't have to pay for. Almost 2 decades of email services, search, and drive space is something I'm glad I never pay for.
In certain cases I do keep data away from Google, I'll never upload all my photos to google photos, or put my media collection on a google drive, and i'll keep certain documents locally, but for the majority of the ephemera in my life, it's a fine place to leave it.
Nothing about my life is really that important or sensitive that security is a must and I need to be completely clandestine, if I leave a trail of breadcrumbs for someone to use to pipe adverts at me, so be it, but I can always stop them in browser with a good ad-blocker or a network level filter.
If I want that level of privacy I can always go down the proton-mail account route and use PGP or encrypted messaging. Although that's not really necessary when I'm just send my GF a gif of a seal playing a saxophone or deciding if I cook fajitas for dinner!
