In a way I agree with you but the issue is... if you decide to leave and not honor your bond, a smaller outfit will be in a difficult situation. A bigger ATO will have better legal back up and if they go to court and lose, the hit is smaller.
As much as I think the way airlines go about the TR, I think flight schools are playing in a different league and the smaller outfits may have a harder time sponsoring FI candidates.
But I repeat... I'm very happy that some of you guys are having your FI rating or upgrades sponsored.
