Some of these issues are excusable by saying they "added too many features too fast" (especially the inconsistencies which the article begins with), but lots of the issues are just caused by Liquid Glass becoming a thing and some "less important" apps didn't get a proper UX test after switching to Liquid Glass design (the whole latter half of the article)...

And that's not excusable - every feature should have its maintainer who should know that a large framework update like Liquid Glass can break basically anything and should re-test the app under every scenario they could think of (and as "the maintainer" they should know all the scenarios) and push to fix any found bugs...

Also a company as big as Apple should eat its own dogfood and force their employees to use the beta versions to find as many bugs as they could... If every Apple employee used the beta version on their own personal computer before release I can't realistically imagine how the "Electron app slowing down Tahoe" issue wouldn't be discovered before global release...
