It was reported that EK need at least 700 pilots. FR has by my quick maths around 3000 pilots (250ish airframes times 6 crews). No HR department in their right mind would hire exclusively from one airline so don't expect them to fill all the slots from FR. Likewise if BA and Virgin start recruiting don't expect them to target FR solely.
I can't see that any loss of pilots will really cause MOL any problems. There are enough people willing to pay to fly to fill his courses up for years to come. Sure his experience base might be depleted but this has never worried him in the past. He has loads of airframes parked up anyway and his pilots are not working that hard at the moment in anycase. A bit of tweaking with the roster would pick up any slack and bring a smile to the eye of the BRK contractors as their pay packets increase.
Given that funding is difficult to find I am surprised that MOL hasn't offered a scheme similar to CTC where he effectively screws the candidate out of more money through paying back career loans in addition to a salary/hourly rate sacrifice. It would lock in the pilot in the absence of having any cash to be able to buy themself out of the "deal".
