My own reason is that I hate internet-protests like this. Someone on Reddit gets some half facts, mixes in with some misquotations, then tries to whip together the internet mob to do their business.
A few geeks moving a few domains away from godaddy will have absolutely no impact on anything, and all it will do is waste the geeks own time.
Do you have millions to spend lobbying Congress? If not, you can do the next best thing: protest in any way that can hurt financially (even in a tiny way - it all adds up) companies that CAN and DO lobby Congress.
