Until GoDaddy actually proves they've turned a new leaf, I think you're going to have a hard time convincing your customers (myself included) that this acquisition is about anything other than money.
It takes momentous effort to turn around a notoriously bad brand, and with such fierce competition, there will need to be some serious benefits to convince me to stick with MT.
Truth be told, if your service is comparable to other services, I'd rather not give my money to a company owned by GoDaddy.
