I agree, Ogie,,,,Dave V. took action.
But at the end of the day...."they can do that brother" will become "Now, they're all going to do that, brother."
When a/c maintenance was part of 501, the local used to tell us "they can do that, brother" with respect to mechanics not doing other carrier's work on AA's ramp. We had to suck it up then, we still suck it up now.
Sadly, i fear that the other carriers on AA's JFK ramp will look for a similar deal as given Qatar.
I would be extremely concerned if i were in fleet service.
