I don't think so. Zagitova's own technique is awful. She's a physically stronger person than Medvedeva, which is helping her. Medvedeva's jumps really started to give way when she got injured (which coincided with a growth spurt). It was probably never going to happen for her with Eteri at her age to retrain with that technique. You can now see how she's looking stronger, and accordingly is adjusting her tehcnique to carry herself across the ice more effortlessly. Zagitova's jumps also started to give way last season -- exactly again when she had an injury coinciding with a growth spurt. The only difference was age (and greater physical strength).
Simone Biles, more often than not, uses relatively good technique on her tumbling, performs with joy, and has great aesthetics to her gymnastics overall. The amount of crap is laid onto the quad girls because their technique is bad, and yet the judges reward it. Most don't have anything personal against the skaters, although some make it so. Proper technique not only prevents injuries, it also gives a jump the best possible aesthetics -- ballon is important to achieve in ballet for a leap to look good, and equally in a figure skating jump. You can compare the way they jump even their triples with Midori Ito - she had a better 3A than any girl currently attempting one, too.
Because there are skaters they do like, who don't get credit for what they do in favour of poor technique.
I do think there's joy, but when the overall skating is so laboured, it's hard to come through. Scherbackova is rather talented for instance.
