I have had to bathe Taz twice in his life. We had a flea problem and had to. But my friends (use to be my neighbors) always bathe their cats. I'm not sure why, but obviously they have gotten use to it.
I didn't see anything disturbing in the video. Although, I did not watch all of it and I watched it without sound. But I could see the kitty meowing it's head off. Hey, it must have needed a bath. It's not going to kill it to get a bath. She wasn't beating it to get it to sit still. (at least in the part I saw)
Yes, I don't think cats need bathes, except for medical or emergency reasons. They bathe themselves just fine.
