Disagree about "adding nothing". We're talking about hardware for nontechnical family/friends, who might not understand the conflict of interest. It's not nice to project your apathy/disbelief that Google would abuse the access onto those people.

The name-calling is really not necessary. Why not make your point on its own merits?

The doc[0] you're quoting continues to list a bunch of things they do collect, including some with no opt-out. Way to cherry-pick.

Even the part you quoted does not exclude traffic metadata.
