I figured this will affect GoDaddy in the long term much more than it did in the short term, when people said "after all the fuss, it seems GoDaddy didn't lose that many users".

The point was that people wrote a ton of negative articles about GoDaddy then, and since that day forward virtually no one will recommend GoDaddy anymore, and instead will (probably) recommend NameCheap or someone else. I would expect the GoDaddy exodus to continue in the next few years.
