It's deranged that people are disagreeing with this statement.
Apple have dug themselves into a hole with Liquid Glass. It's ugly and illegible, so they're having to dial it back and its eventually going to loose any of the "Glass" look about it, which is an embarrassing U-Turn when the new design is the MAIN new thing about ALL of their New OSes. The obvious solution is add a setting to toggle it on or off (or god-forbid, enable OS 'Themes") and then everyone can just shut up about it.
Design is always subjective. You can argue about change being good or bad, or whether you like the glass look or not forever, but that's never going to change. BUT you can be objective about it when it comes to its practicality and utility, and transparent, illegible UI is objectively bad design because if it's not user friendly, accessible and usable, then it's a bad User Interface.
