Google’s core DNA is search and engineering, though some would say
engineering that is driven by the economics of search, which makes
it hard for the company to see the world through any other lens.
Apple’s lens is that of product, design, and experience. This
allows it to make great phones and to put emphasis on privacy, but
makes it hard for them to build data-informed services.
Facebook’s DNA is that of a social platform addicted to growth and
engagement. At its very core, every policy, every decision, every
strategy is based on growth (at any cost) and engagement (at any
cost). More growth and more engagement means more data — which
means the company can make more advertising dollars, which gives
it a nosebleed valuation on the stock market, which in turn allows
it to remain competitive and stay ahead of its rivals.
