People in positions of authority need to be careful with their words. They might not be intentionally misleading, but it is possible that they make a remark without thinking it through and others end up believing.

It happened to me. The CTO of the company I worked for moved to another company and recruited a bunch of us from his previous job. He made tall promises, none of which worked out. We were annoyed at the time, but I now realize he didn't intentionally mislead us - he was just overly optimistic about his abilities and his own faith in the new company he joined. It was a disaster for everyone he recruited from his previous job.

Everybody has a price, everyone has a breaking point.
