Re: you get an invasion-free Gmail if you pay for it.
"No, you don't. Where are private paid options?"
Do you know how to use the internet?
"Transparency is part of Google's DNA. We work hard to earn and maintain trust with our customers through transparency. The customer – not Google – owns their data. Google does not sell your data to third parties, there is no advertising in G Suite and we never collect or use data from G Suite services for any advertising purposes."
Essentially, you have the choice, pay for GSuite if you genuinely don't want Google using your data for anonymous data purposes, or use the free services as much as you you like (of which when you add them up, add considerable value, Mail, Calendar, Office, Maps, Photos and so on...)
