My post was hypothetical; I'd imagine Google does have rules and procedures in place to keep your data private vis-a-vis random voyeurism by employees (but how would I know?)
I do find it amusing that the control of the web and computing by a handful of companies is now apparently ingrained in some people's heads as axiomatic, such that any apparent criticism of one oligarch is automatically a defense of the other.
I'm not defending Google, I'm just pointing out that, unlike Facebook, their founders haven't declared the "Age of Privacy" as over.
FWIW: I dislike Facebook but I use it anyway because that's where everyone I know seems to be. If I could substitute it for another service that lets me more tightly control who sees what, then great.
At least Google has aspirations of not being evil. Mark Zuckerberg only seems to aspire to eliminating privacy altogether.
