While
@somebozo went off on some trip, of which less said the better but I think you are missing something here which perhaps is reason why you can't understand the fuss over this.
From the Pakistani perspective those teachers are Turks. To them they don't look at them as Gulenists as most don't even know Turkish internal politics. So in a sense these teachers have made a impact in their respective schools as 'Turks'. They have been hard working and built up very good relationships with students and locals. So now to be told they are bad causes disbelief with those who know them. Don't forget it's not like they have horns on their heads. In a sense this shows how pro Turkey Pakistani are. Even when they are told they are no good they just can't come to terms with it.
And don't forget it's not like these people shot, beat up, or look like ogres. They on the face of it appear as gentle, caring, hardworking teachers many of whom are females. Hope this explains the hullabaloo.
But look at the end of day Pakistan is doing what Turkey wants.
