How I made every tech company that I may ever want to work for in the future hate me, or “GO R Consortium!”

It turns out that when people tell you things, you should listen. Like when Joe Rickert of Microsoft says “this is not news, please don’t repeat what I’m about to say”, you should maybe take note and keep your mouth shut. I’m not quite sure how I missed that, but I did. So on Sunday
