They chose a default, the choice to change that default is still with the customer.  It&#x27;s also very granular so you can choose for each individual line how you want your service.<p>While content manipulation would give pause for concern, as it does with Comcast&#x27;s data cap notifications, that isn&#x27;t what T-Mobile is doing.  They&#x27;re not altering the traffic, they&#x27;re altering the transport rate which is very different.  By lowering the bandwidth of certain content types, they&#x27;re triggering the adaptive technologies employed by services to behave differently.<p>One of the EFF&#x27;s gripes was that the pipe constriction was indiscriminate and thus services that didn&#x27;t employ adaptive technologies experienced buffering and stuttering issues.  That&#x27;s probably the only legitimate point they made.
