About the actual usage and activity of the devices in the wild. The network that does that is targeting western markets where the availability of devices that are vulnerable is dropping steeply - not fast enough, but still.

I've yet to also see a single worldwide USAGE statistic that would reflect that dashboard. Whatever Google is counting is not the users that actually download and use apps (and are thus vulnerable) - pretty much all stats I've ever seen (even on apps with millions of worldwide downloads) have significantly higher update rates. Hence - misleading.
