Revving engines too hard?? Please explain that, I am clueless about flying a plane.

The trick to save fuel in the short-term, ended up costing more in the long terms by means of having to replace engine?

Cheap/short-sighted pilots/IndiGo management or underpowered engine fit by Airbus?

..susceptible to mid-flight shutdowns.. - With the Boeing issue, I am trying to understand if passengers life were endangered? Who is to be blamed for the issue? Pratt & Whitney for making an engine that is not efficient or IndiGo for trying to act smart or Airbus for poorly designing a plane/insufficiently training(ipad training) the pilots?

The U.S. Federal Aviation Administration hasn’t established any connection between the climb procedure and engine problems, she wrote in a text message, adding that the safety of passengers, crew and aircraft remains the utmost priority. - FAA let Boeing kill 2 planes of people and only stopped them after rest of the world grounded the flight. It's not comforting to quote them to assure safety.
