Where are you getting that curved lines are easier? You usually have to redraw a few times to get a nice curve. Straight lines are always easier, even in the 80's there was no issue drawing a straight line. I just quoted back your demand for credentials verbatim back to you, you asked. Hasbro is primarily at fault for the quality of G1 animation. They had studios churning it out at ridiculous speeds to save money as always. I think animators have carried the G1 shame blame for too long.
