Isn't Speedtest's huge dataset of Internet speeds mapped to time, location and IP address, as well as data on VPN usage (a user checks the speed of his/her direct connection then turns VPN on and checks over that too, all within the same session) such an asset?

I doubt they didn't collect all of that.

P.S. Now marry that huge dataset with services that Accenture provides, among others:

"In February 2025, Vice News spoke to a former Accenture employee under the condition of anonymity. His project on the WhatsApp team for Meta required him to sift through images and decide whether or not they depicted child sexual abuse, which he coped with "through a lot of substance abuse". The former employee claimed to have witnessed multiple missed opportunities to protect children, and alleged that one colleague had previously been arrested for possessing child abuse materials. In a statement, Accenture said they are "committed to helping companies keep their platforms safe through services such as content, advertising, and compliance reviews."¹

Hard to see how that is remotely worth $1bn.
