I didn't want to use it either. 
1) the camera always streams to my-dlink (skeptical of streaming video to a third party server with no control over the data or access logs) 
2) I don't really need to go to my-dlink to get access to the network since it already support dynamic dns 
and another thing i noticed is when i disconnected my-dlink it reset the whole device.. kind of weird, the option should be able to dynamically add and remove when needed not a complete reset.
