Doubt any one was really surprised. Some people were pretty peed off though.

Anyway Chinese economy is half based on illegal copying of other's products/ideas.

Also Hobbyking is back at selling Deans style connectors. Slightly tweaked but really the same thing. Doubt anyone will ever stop them. Hell they have even copied TRX and EC type connectors.

The fact they made a line of their ESC's look very similar to Castle ones I doubt it is going to fool many people that they are pretty much the same thing or of similar quality. Not in this day and age. And if some people think that they are getting pretty much the same thing they will probably regret it sooner rather than later.
