Perhaps you should research a little more before you fly off the handle there mr Fork. Term 3.10.2 and 3.10.5 directs the pilot to follow the approach procedure to the MAP and then follow the MA procedure. It also defines the MAP among other things as "the point of intersection of an electronic glide path with the applicable DA" and in almost every case this corresponds to the middle marker. So you MUST continue to track towards the runway and not turn left until arriving at the MAP.
If you turn left before this point then you are operating outside the requirements and regardless of how professional ATC are you will be penetrating their departures and will be reprimanded. I have seen this happen.
