This phrase has rather a lot of qualifications which make it trivially easy to circumvent. For example, Google might associate the data with a different account, an internal "ghost" account that you specifically don't use for Google Fiber (but which is identical to it in every way).

I for one would like to see ISPs make an effort to construct systems where even the owner of the ISP doesn't really store any information. For example, they may store differential information about traffic spikes, to help avert DOS attacks. But other than that, they only do what they get paid to do: shuttle bits back and forth across the last mile of internet.
