Jacky-o, you better pick your battles. This is not your battle nor does it concern you. If you wanna make it yours, be very very careful. Everyone knows why you chose to do your license in Indonesia.
Oh, and the instructor, who saved your life when you had the power loss on upwind, sends regards and wishes you good luck!
Again, be wise. Putting down the people who have taught you how to fly, is not a wise decision.
And it certainly shows what kind of person (and pilot) you are.
