He's objecting to the Government asking Google for the bulk data they collect. They can do it three ways:
* Just ask for it, and say "due to the third-party doctrine you have no legal reason to refuse"
* Show up with a National Security Letter, take the data, and say "this is OK due to FISA oversight. BTW, you can't tell anyone about this."
* Copy the data as it passes through the thoroughly suborned telecom infrastructure, without even asking.
Bulk data collection by Google is potentially bad. Bulk data collection by the Government is worse - Google can't arrest me.
