Whether or not they have implemented anything yet, "addresses concerns by the likes of Microsoft and other tech giants" should read "addresses concerns of non-US populations"...about the ability of the US Government to pry into the private affairs of non-US citizens.
Not that the US Government gives a flying fuck about the views of non-US citizens. If the US Government finally starts to behave decently and respect the views of non-US citizens (even for the most bogus of corporate-funded reasons), it's a start...
It's very fashionable to decry things we don't understand. Dowsing clearly works; my father called the local dowser in for his house in a remote part of SW Ireland. I watched him walk back and forth across the land, rods twitching, and eventually he hacked his heel down and said to "drill here" and we'd get "water for a family of five and to spare". Drill he did, we dropped down a remote-control DanFoss pump, and sucked on an aquifer that never failed, even in the drought years.
OK, they guy knew all the land thereabouts: he lived locally. Maybe he just knew the exact path of every underground watercourse in the neighborhood, but I doubt it. As a scientist, I want replicability of the observation (no problem here: he and several others do this for a living: no charge unless the water flows), and I'd like an explanation of why (none yet)...but equally I refuse to dismiss a phenomenon simply because it has no explanation yet. If we did that we'd still be living in the dark because we couldn't explain sunlight.
