I don't think Uniqueorn wants BC to have control, he wants the features/big guns rolled out as soon as possible.
He wants the opposite of what you said - more control not less.
Well, we have 2 options:
1. Take current version of Nxt and keep develop it in our own way, without changes added by BCNext
2. Wait for 2nd and 3rd parts of BCNext's plan, read them and decide if we need to follow them. If we don't then see point 1.
In any case we lose nothing. Nxt already has more features than Bitcoin.
