For money? Lots of people.
Does Google have a fascination with only hiring people that want to write dissertations about their project of the month?
Your post begs the question, though, why it had to be served as dynamic content in the first place (if it actually was which I'm not sure it was) when it would've been the obvious thing to use just plain HTML. I'm thinking about authors putting in considerable effort into publishing content on G+ (or other platform for that matter). Why would they use an authoring tool that is exclusive to that platform when we have HTML? Why wouldn't they care about their docs being inaccessible if the platform dies?
Why shouldn't it be served as dynamic content, if that's how the system works? All social networks and even most blogging platforms are built like that. I'm not talking about just the contents of individual posts, I'm also thinking of their ranking, as well as smaller details such as user names hyperlinked from the post body. All the data and metadata is stored across a large number of databases. I don't know of any products similar in scope that consist of pre-rendered HTML. Sure, you can scrape or render the HTML at a point in time, but that opens a new can of worms.
