I think you fail to understand something here. The objective is NOT to get people to drop GoDaddy. The objective is to get people and companies to understand how SOPA can be harmful and hope that they oppose it. Dropping GoDaddy had more to do with people's personal beliefs in not using the service for primarily two reasons (albeit they are not the only reasons):
1. Disagreements with the stance in which GoDaddy represents (SOPA, killing elephants, etc...)
2. The poor service many have echoed
The hope was that GoDaddy would recognize why the public (mainly their customers) believe what they believe in hopes that it would prove a point and influence change.
Now that GoDaddy have publicized their opposition of SOPA due to the outcry of the public, continuing to try and damage their business and get customers to leave is nothing more than mob mentality for all the wrong reasons and losing sight of the main objective of the original goal.
