This doesn't make much sense to me. Unattributed heresay has limited historical value, perhaps zero given that the view of the web most of the weights-available models have is Common Crawl which is itself available for preservation.
I suspect the idea is that sometimes breadth wins out over accuracy. Even if it's unsuited as a primary source, this kind of lossy compression of many many documents might help a conscientious historian discover verifiable things through other routes.
