Originally this was a reply to this article about a Windows feature called Recall, but there's a good argument the author's concerns resonate far beyond Windows and Meta to proprietary generally.
In the renewed spirit of Screw Microsoft today I found that video "https://youtu.be/DwiHog2leMM?list=FL7oNgzhY82m2rFR_j5lW9vw&t=393"
I don't know how much of the video is still relevant as I've long stopped using Windows again to the point that my Cert has expired. Anyways, sorry for the late response. Good Luck!
