> Google's extreme overreaction to someone trying to get some very basic information about the other set of employees is what's concerning.
Probably this is what set them off -
"...Most of them are people of color and are supposedly involved in the labor of digitizing information. I’m interested in issues of class, race, and labor, and so out of general curiosity I wanted to ask these workers about their jobs. I am aware of internal mechanisms for discussing labor issues with Google, and had no intention of defaming the company..."
A lot of times you can dig a hole for yourself that wasn't there by trying to explain things. Just a, "Was I breaking the rules? Okay, my bad, I didn't mean to. What was I doing? Eh, just screwing around with a video camera, exploring, I won't do it again if it's a problem" probably gets you out of there without hassle.
I mean, his simple explanation covers mentions race, labor, labor issues, defamation, legal contracts... that would scare the hell out of anyone. If he'd just written, "Hi guys, I'm just learning about Google and I like the company. I didn't mean any harm - I'll make sure not to do that again if it's against policy" then that probably would have been the end of it.
