This is basically it. There's a thing I've noticed, I like to call it the "inverted reason list". It's an upside-down ordered list of reasons to do something, delivered to a skeptical or hostile audience. The list is ordered such that reasons the audience will like are delivered first, as if they are the most important, and the reasons the audience will hate are delivered at the end, as a side-thought.

"and oh....it turns out open offices will save us $5m a year in facilities costs." is usually delivered at the end, when nobody is paying attention anymore, because it was preceded by "free snacks at every 25th cube!" and "will allow you to configure seating to keep your team near you"

For work that requires lots of talking (or not lots of deep thinking), they work "ok", but for knowledge work, they're basically the worst idea ever conceived outside of sending all your coders to rock concerts all work day and wondering why nothing is getting done.

Where I work, most people get or split offices, but we can work in a few other places, including an open work area. Most people hate working there because it will inevitably have somebody on speaker phone having an argument with their health insurance over an unpaid bill, and that conversation will go on for 2 or 3 weeks solid. Appeals to management have basically been ignored, and now we're getting ready to move to a new facility that's all open space.
