Google already have 5,000 odd photos of me anyway in Google photos. I'm screwed either way.
Plus friends and family inadvertently give Google/Facebook (etc) your personal info via tagged photos, contacts, DMs without your consent and they gather/link/sell this collateral info to the highest bidder without anyone being the wiser.
That attitude is exactly what got you into that mess.
There's no reason to believe the mess couldn't get any deeper, so backing out now doesn't have to be useless.
