As someone else mentioned in a commment, Wikipedia averages about 2 edits per second and almost 600 new articles daily. A legitimate use of something like this is having Google search results lookup Wikipedia pages more often and in a timely manner. As the article states, it also provides SLAs for the APIs/service. So let's for example say Big Movie Star X dies, but the free API for downloading content is down for the day for maintenance, well now Google's flagship search product is serving stale/outdated information. This product provides businesses a means of reliably depending on an updating source of data.
