This is unfortunate... Especially considering I just bought this app a couple of days ago.
I'm not sure what all the legalities of this case are, but I hope these widgets don't get permanently taken off the market. I think the developer is providing a product that people want and it is not a direct replacement for Sense UI. I'm only using the clock/weather widget and none of the other stuff, for example.
I guess we'll just have to see how this plays out.
