content: I guarantee this thing will be DISABLED on that port in upcoming release now that the NSA was caught. If it was a deliberate feature my prophesy would not be true. But I know I will be shown correct.  Because , you are partly right, its NOT a bug, AND NOT a feature, its a slippery evil back door. NSA will set it to an internal port in future , or force it to use local wan "IP subnet" , or add password, or turn it off. I GUARANTEE IT! They got caught.
