I don't think they do, but if you think that I expect it's because they're part of a small team who designed/developed the device and software and do not have very little media training and do not appear in front of a camera as their day-to-day job. This might be the first time they're appearing in a published video ever. As a developer I'm not sure how I'd appear in a video, it may well be 'creepy' as you describe, I'd be very nervous and self-conscious about it. I think I'd also feel pretty awful if I came online afterwards and read about how people thought I was creepy.
