Harry,
I read his comment differently.
The TRUE issue that exists is the fear a pilot may have of losing his job which is why, in most world class airlines, revealing a medical issue is non jeopardy. They WANT you to reveal issues so that they can keep a potentially unhealthy pilot out of the flight deck until he is healthy again and there is no fear of job lose.
That does NOT exist at EK - sorry - don't try and tell us that it does. Didn't exist at that little low cost German Wings either since the pilot was concerned with loan payments ( to pay of his training) or many other airlines.
It is easy to blame the pilot/person. The issue though is the system that will leave them high and dry. If he has to choose between his paycheck/career/feeding his family or coming forward if he believes there is ANY risk he may well decide to stay quiet. Particularly if they "believe" that they do not present a risk.
