No other company I can think of has invested in such a rigorous Privacy review and support structure in an attempt to reduce risk. Other BigCorps do take it seriously, but get by with much less investment. Despite this, FB et. al. are keen to poach Google Privacy employees, because there are very few Privacy Engineer in existence and Big-G pioneered modern day corporate privacy efforts. Google is a huge target for hacking and public criticism or even loss of human life due to product decisions, especially because the products are so ubiquitous and widespread (browser, mobile OS, search engine, Gmail, ad network, etc). See subjects such as Differential Privacy.
