Passage Summary: A manager is advising against switching to a new, supposedly 'user-friendly' software. He points out that at other companies where they made the switch, the employees are still secretly using the old, 'difficult' software because they prefer it.

Reasoning: Other companies that switched to the 'easier' software found that their employees still preferred and used the old software whenever possible.

Analysis: The manager is using the behavior of employees at other companies to cast doubt on the benefits of the new software. If employees are 'unofficially' sticking to the old system, it suggests that the new software might not be as easy to use or as efficient as the advertisements claim. When looking for the best-supported inference, focus on the idea that the 'ease of use' of the new software is likely being overestimated or that the transition is more difficult than expected. It's a classic case of human behavior revealing more than a marketing brochure does.
