I must be some USB-C unicorn as I can't think of ever having any issues.
I have had a couple of USB-C hubs and they have worked for both me and my partner. All my work machines are USB-C only and literally the only issue I can remember is where in one conference room the USB-C to HDMI output only went to 2 of the 3 screens on the walls but I think that was something unrelated to the USB-C connection.
Now I don't push my USB-C hubs hard but did run ethernet, HDMI, and USB-A device or two pretty often and everything worked as expected.
The author's main complaint is that the network was being downgraded to 100baseTX. If you aren't doing a lot of heavy local network activity, you might not notice if you are being downgraded.
Since much of my USB-C hub usage was during COVID and work at home, I did do a ton of speed tests and don't remember seeing any issues with being downgraded but if it was random then I might not have noticed.
