It would help if you had the first idea of what you were talking about before you posted here !.
The the traffic imformation and WX radar pictures are data linked to you mode S unit from the ground radar station so I cant see how an ATCO would want to turn off this function as it would increase his workload insted of decrease it , yes ATC can switch you off there screens the S in mode "S" is for selective this will remove the clutter from the screen as it will eliminate from the controlers screen traffic that is below controled airspace but climb into that airspace and you can be sure that you will be on the guys radar screen with the aircraft ident .
As to the cost you cant value you life very highly , this is very cheap TCAS/ WX radar system that will fit most light aircraft those who have fitted the Garmin 430 already have the means to display the imformation so I cant see the problem if it costs me a few quid to have traffic/wx data that at the moment is the preserve of the airliners and biz jets.
Bar Shaker the first time that you have to work your way around an active WX front with this equipment you will see just how good it is and wonder how you ever did without it.
