Well, this is supposed to be a professional desktop machine. I don't want to run my work machine off of wifi that could randomly disconnect in the middle of meetings though. I know I'm not the only one. They could have spent the 3 dollars per machine it would cost them to add an ethernet jack, but instead they're going to have you spend $20 on some adapter dongle.
As for USB-A, there are tons of peripherals still in existence out there. Maybe you're fucking loaded and you don't care about just buying everything USB-C, but that's definitely not the case for everyone. Suppose I have a nice USB-A optical mouse and mechanical keyboard that I like for example, or a really nice $200 audio interface. I guess I need to buy yet more dongles, or throw them away and replace everything with USB-C peripherals because some 20yo on HN says that USB-A is legacy. Thanks Apple. You definitely value user experience above all else.
