Hi Ravo. Most big companies are paranoid, and rightly so, about IP leakage. It costs them billions and its not just stuff going to China so they tend to lock everything down. I do stuff for Ericsson AB, Bell Labs and Verizon they even install software on your PC that even locks down the USB ports so you can't copy anything off.
Google Drive and Google Docs makes this easy, whether people are doing it deliberately and copying information there that they will pass it onto someone else later, or just being not too bright and storing corporate data where others can see it. So they just block access. Google also have access to every byte that's in their storage. I've done work for Verizon, AT&T, Ericsson, China Telecom, KT, and they all do it, as do many large corporations.
I'm not suggesting that they would be interested in our endurance results, but if I work for Verizon, which I do, I'm not accessing Google anything from that secured device.
Their other concern is that Google mine the cache in a users PC for any information that they can sell. Google don't actually write Chrome, they just take an opensource thing called Chromium and put their brand and all the data mining stuff in it. If there is something sensitive then they have full access to it. You can see the data going back to their servers. If you ever apply for a job at Google they look at your entire history stored on the PC and if you ever searched for Trump in the last 10 years, even by accident, you are not getting an interview
The other issue why they block it is contractual. AT&T have a Strategic Partnership with AWS for Edge and VPC so they can't have their employees accessing Google from their corporate devices.
For some strange reason Google are the Boogeyman when it comes to this but its a situation they put themselves in.
