Profits have also doubled. Gravity did lose a few customers: Some objected to what seemed like a political statement that put pressure on them to raise their own wages; others feared price hikes or service cutbacks. But media reports suggesting that panicked customers were fleeing have proved false. In fact, Gravity's customer retention rate rose from 91 to 95 percent in the second quarter.
