GoDaddy, with 50,000,000 domains, has lost almost nothing, about 1000 domains, when you factor in new registrations and new transfer-ins.
We would need the historical records to see more into this.
Hell, it might even look like their registrations and transfer-ins are up due to being in the news.
I seriously doubt that GoDaddy gives a shit about this.
Their domain business is a complete "loss leader" operation that costs them about a dollar of loss on each domain they sell.
Hosting accounts is where it counts the most for them and I can tell you few, if any, people will be transferring hosting accounts out as it's a complete pain in the ass.
