The Apple universe seems to be a place where sentiment is driven by tastemakers and small-group consensus, not the mass of actual customers. So it doesn’t need to be a dominant complaint to have a big effect.
The griping I read about Liquid Glass is from the unhip nerds on HN (like me). I don’t actually know what the industrial designers and graphic artists in their Soho lofts think. I asked an exec designer that I know IRL and got a shrug.
