Are you sure you did not get it backwards?It shows that they do care about their users, and they are willing to do whatever it takes to make them comfortable. A few Redditors started a cause to donate money to Wikimedia in return to ask them if they would acknowledge the fact that GoDaddy is/was Pro-SOPA and they should plan on switching their domain over somewhere else.
Jim is also a Anti-SOPA guy, he had the idea to move the domain once the news was out about GoDaddy supporting SOPA. Wikipedia saw an opportunity from their users that were encouraging them to switch.
Along with many others, I also agree with the choice WikiMedia recently made.
Opposing SOPA is a must for wikipedia to maintain neutrality. Else, soon you will see that most of the so called controversial articles on wikipedia are no longer available because it will make it mandatory on the part of wikipedia to remove them.
And moving their domain from Godaddy is the right thing to do.
This is the logical next step part of a much longer trend on Wikipedia, that of the solidification of power in the hands of a few, which has been happening with the editing for some time.
