What do you mean new generation? It was Zuckerberg who said “I want to stress the importance of being young and technical. Young people are just smarter.” [1]
I remember being in Sixth Form and then an undergrad while Facebook was in their "web-scale" days: there wasn't (yet) anything untoward being reported (besides the "dumb fucks" quote) - so I like to think that Facebook's principles, then, were more "let's see where this goes" - which isn't much of a principle, I agree - but we were all re-projecting Google's and Apple's story onto Facebook: something along the lines of "they'll make billions of dollars from giving people what they want, how can that possibly be a bad thing?".
So I'd summarize Facebook's then-"principles" as believing in their own naïve optimism about the power of connecting people, but we were all naïve with them - so while it's easy to criticize Facebook now, almost a decade after the corruption started, which of us can point to our own Slashdot or Digg.com comments made prior to ~2012 that predicted this?
