Because the company is a king, and the employees are the property of the crown?
I found the migration of experts from CMU to Uber fascinating — for two reasons: 1. The geographical proximity in which the acquisition occurred (i.e. a rust belt town with an awesome CS school and a well known Silicon Valley startup on location). 2. The moving from the academy to the private sector of said professors/researchers happened in a way I hadn't seen before. I mean lots of academics work within industry at some point, but this move seemed to carry more weight in the media — maybe because of the institution involved.
Anyway, with that said, lots of the articles and speculation I read about it, for better or worse, painted the acquisition of academics by Uber as a bit unfair. I.e. Uber could and did pay way more than CMU and provided super interesting problems maybe outside the realm of what a professor normally faces in their research, I don't know. It was the "unfair" element portrayed in articles/opinion pieces I based my wording off of. I am in no way suggesting these profs and researchers did anything wrong or did anything but make the right choice for themselves, something we all have to do.
I digress. Word choice noted, problematic history and other associations noted and hopefully I cleared up my choice a bit.
