“Given addresses” != adoption. Hell, I had to disable it in osx because it breaks the damn hotspot connection functionality. Wasn’t using it, it’s just there, breaking shit and being useless.
That’s Apple’s fault. Why are you blaming it on IPv6? Oh, because Apple can do no wrong.
Google's stats are tracking the percentage of people that reach Google over IPv6. That means they've not just been given addresses, but they configured them and are actively using them. How can that possibly not count as "adoption"?
