It's easy to say "buy a box and connect it to the internet", but that's consumer grade equipment. If my computer goes down, it only affects me. When an instance goes down, it can affect thousands of people.
I'm not saying they couldn't find a less expensive solution with AWS or Azure, but they need a solution now. They don't have the time to learn a new solution, design the system, and then implement a new backend while people are swarming to their instance. Migrating to another solution (even the above "box") means significant downtime for 50,000 people.
