Not until just now I didn't. Do they not have a smartphone? A personal laptop? I'm waiting for something to build as I'm typing this right now. On a separate computer. I would never go on Hacker News on my work computer.
Why would I use a device to do personal things that they MITM everything I do on it? Privacy is too important to me to give it away like that. I'm sure all traffic on the corporate network is logged. Why open myself up for grounds for termination if my company hits hard times and wants to lay people off?
