Why separate out products developed internally versus acquired and growth? There is an almost moralistic element in the tone of “well they just bought it”. Sure, they bought it and grew it into a behemoth, plus what really matters is not the provenance but how much money it makes for them. Plus, it’s reasonable to call YouTube (and instagram, which also gets the same treatment) two of the all time best corporate acquisitions. It’s not easy to buy a company and grow it like that.
