Re: @diodesign private v public
"Dad runs the generator and it supplies power to our house" is a world away from "FuckYouCorp supply power to 1 billion souls". In the same vein "employee #18642 whom can be sued into oblivion if he gives us shit can access your corporately owned files that are located on our corporately owned servers" is a world away from "any of these employees here can access the personal files or the corporate files of your personal company of over one billion souls on this utility-class public cloud we stood up".
Scale changes things. Also, ownership of that data maters. Microsoft don't own the data that I put into Onedrive. I do. And it doesn't matter what their Ts&Cs say, they legally can't claim ownership of that data without my say so: the laws of my nation say so.
