Now, that's often not my experience. You can find some of the worst examples in anything made by Microsoft; Teams and Outlook are particularly bad, as you said. I don't poke around out of curiosity, I fumble around out of frustration with their slow, ugly, bloated, unreadable software. Apple sucks too, except, instead of being unbearably slow, they're honing in on making their UIs less readable and less intuitive than anything that came before.
