Thinking back on history, interesting that Apple's old nemesis MS is not one of the names involved here. Not a 'friend' of any of them, but on my intuitive ethic-ometer Apple (barely) retains the top position.
Apple and Microsoft are practically buddies in this stuff, they both make money primarily by selling products and services to customers, and have relatively less overlap in their target markets than they ever have. Meanwhile FB and Google make money by mining users for data and selling ads. It’s a pretty different business.
