> historically they have never told my spouse about my affair

Have we forgotten Google Buzz? Google changed GMail to publicly list the people you email most. In one case, this de-anonymized a woman's blog and enabled her abusive ex-husband to stalk her. https://fugitivus.wordpress.com/2010/02/11/fuck-you-google/

This is IMO the most likely way that "bad stuff" will happen: not maliciously, but through privacy-invading misfeatures connected to pushing people to share more.

Thats 12 years old... I think it's a real testament to Googles privacy behaviour that amongst their 2 Billon+ users over 11 years, there are no fresher news stories that come to mind.

Compare with facebook/instagram, where it seems every other week someone messes up the privacy settings and posts something to an audience they didn't intend because the product is deliberately designed to encourage accidental oversharing.
