I agree about the personal details being released - a big 'no-no' in my book..
On the other hand, someone either IS or IS NOT up to the job of commanding a flight. End of. There are people's lives at risk and the Captain of an aircraft has a huge responsibility. If he isn't up to the task then someone has to take responsibility and 'call him out' / fail him during sim or safety checks.
Sorry if that sounds harsh but I can't see any other way.
