It's not obvious that the data came from AOL or Yahoo. The initial papers describe Brin and Page's attempts to design their own web crawler. Google collecting the data itself, instead of getting it from an incumbent, undermines the article's thesis quite a bit.
That said, one interpretation of the PageRank model is of a user randomly clicking from page to page, occasionally giving up and starting over. AOL would have access to data like this, which might help them refine the "damping" term in the PageRank model.
