I was calling out that he failed to do the latter, and my obligation is to explain why a company might not want to, or be able to, implement those changes.

The fact is that I'm not wrong about him glancing over an important part of his proposal. If you write an article advocating companies undergo radical shifts in their organizational structures, then as someone who is regarded as an informed commenter, you have an obligation to tell people the pitfalls of such a large change. Again, when you don't do that, it's called cheerleading.

He didn't include any discussion of the downsides, or the upsides of hierarchical organization, so I'm not wrong. I should have used a more tactful phrase than "lip-service," however: it's more loaded -- perhaps even derogatory -- than I intended.
