Even if we drink the kool-aid and assume 5000 subs left early (lets say 2%) it's the people who essentially had all 7 new pieces with all 35 materia slots filled, 2 days after the content released and were back to activating macros soon after. So they had a tantrum and hit the unsub button. Because people didn't flock to the market board to pay tens of millions of Gil to furnish themselves in a new temporary best.
tl:dr, Who cares, right?
