FF, the point is this person, "Bird On" is publicly soliciting for DECs at EK and representing that it's a good option. It seems worthwhile to point out that he's wrong.
GF, the "moral" aspect to this issue is that EK changed the conditions for upgrade to suit their economic needs. Many (most?) of us didn't come here for the "quick upgrade" - we already were Captains. However, Emirates had a 10 year tradition of upgrading from the right seat. We trusted that and decided to wait our turns. Can you imagine that they suddenly changed perverted the rules so much that in some cases guys are hired DEC with no experience on type while 3 year experienced guys cool their heels?
Like WK, I don't hate Dubai or EK and plan to be here for the long haul. That doesn't mean that they are beyond criticism nor are guys who use an unjust situation to their advantage. To answer your other question, I wouldn't do it and haven't in the past when presented the opportunity.
