The formatting of the article ("Blog Image 3Until recently...") strongly suggests this was copied from somewhere else. As for the content - I'd say a tl;dr is "first mover advantage" followed by network effects. Assume you wanted to provide a service to the Internet at large, so you went to where you can get the best and cheapest connectivity, and the first movers had all the advantage, at least in a time where latency didn't matter because all end-users had was a 56k modem. And ideally, you went to a place where you knew other big dogs are, because they will have ironed out the kinks, making it less risky for you - in a city where there are tons of existing large names you can expect a way more fault tolerant network than if you go to some small town in the outback where one drunk backhoe driver can take out the entire town's electricity or network. These days the calculation is different - customers have high bandwidth these days but also they are highly sensitive to latency, so you gotta be as close to your audience as possible, and you build your entire architecture to be fault-tolerant as compute has gotten incredibly cheap.
