I keep literally all private data in Google. When I opened, refinanced, paid off my mortgage with Chase, I was inundated with calls and mail because my bank sold my data, account balances and contact info. Somewhere within Google is all of my private email and AFAICT, they haven't ever sold any data from it.
Google does some bad stuff. They sell access to you, not your data.
When people talk about "Google stealing your data" they are referring to non personal data related to things you buy so that advertisers can target their market better, they aren't like trading secrets and tracking where you go so they can jump out and I dunno, scare you or some shit? No it's just for as revenue stuff. They aren't even serving you more ads they are just serving you more accurate ones because those will generate more revenue from advertisers. Nothing is shared with them like your name or address or even your age really (just a general age group)
Yeah, as a heavy Google user I would use this if I had a reason to use a VPN. Google is scraping all my information anyway from my Android phone, my Google searches, and G-Mail, Maps, etc. They're not going to gain any additional information about me from usage of a VPN.
This is probably true for anyone using Google One.
If I had an iPhone or used DuckDuckGo or Firefox was taking other security measures, it's probably pointless, but I've just gone all in on only Google have any of my data.
