My personal take on this is that it is about money. The theme developers have made a lot of money by introducing a theme that locks users in. Now they need to spend the money to help users and actually create a theme that doesn't lock a user in and they cry about it. They say this is about users. No it's not. If it was about users then the theme would have been portable from the start. They wanted to lock users in an be make money from them. Now when they have to spend the money they have made to assist users they moan. Do the right thing.
