Some objections to your statement:
It's difficult or impossible to know what data you're "handing" them.
Even if you try to stop handing them data they still collect it. See: google collecting location data.
They use fingerprinting techniques to track you even though you aren't logging in or submitting any data to them. Nowhere in that scenario are you handing them data, they are harvesting it.
But yes, on the face of it if someone clicks "I agree that you collect data" they're on their own. But reality is more complex than you let on.
I use LineageOS on my phone, duckduckgo search engine, maps.me geolocation and my own local mail service, etc.
For those who care about the privacy and understand that G should GTFO, it is extremely easy.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
