Good set of slides. Companies are more likely to be afraid of the other risk, which is why SSL interception is used - when malware makes use of it to avoid detection.
Security cuts both ways. I think the most important point is that the user should be in control of the traffic, which means knowing whether or not interception is being used.
Yeah, it's a balancing act, and there's certainly a desire (and probably even a legitimate need) to monitor encrypted comms for malware C&C channels, data exfiltration, etc.
Your view seems to reflect a similar nuance as my own. Administrators need to weigh the risks and benefits as it relates to their own environment, and users should at least be aware that such monitoring is taking place. Beyond that, there's some technical challenges, but I see the bigger issues as political and expectation vs. reality alignment.
