Consumer data privacy
In wake of recent MTR misuse of customer's personal data, I'm not surprise to find below line in the terms and conditions of HKBN's service terms and conditions.

It is true that consumer have no choice in this area where we can only choose not to use internet service if we don't agree?

Below terms pretty much means they can do what ever they like with the data.
