I think you're confusing the map with the territory. What these people hate is that their job requires coordinating resources in far-flung parts of the world, all with different waking and operating hours. If time-zones go away, they still have to deal with the fact that a plane isn't going to depart Shanghai until an hour after sunrise, or that the post office won't deliver the packages until just before solar noon. But now they have to keep track of the offsets in each city manually instead of applying the agreed-upon TZ offset. Time-zones acknowledge a fact about our world. Humans living in different places wake up, work, play, and sleep at different times. These times are (loosely) encoded in the offset. Get rid of that offset, put everyone on UTC, and you lose some information in the process.
