Boeing is installing wifi transmitter/receivers on the new 787, this means tthat Boeing is not overly concerned about trasmitting devices.

To treat all transmitters equally as 'transmitting devices' is about as sensible as considering all aircraft the same because they are both 'flying machines'.
Building WiFi into an aircraft means it is fully integrated and tested as part of the aircraft's systems. That's rather different to e.g. cellphones operating unplanned and uncoordinated and transmitting at 100x the power.
