From my own experience, and from what I got from the article, the lower quality full duplex BT is only part of the problem. The major issue is that the mode is selected automatically on macOS. I never had this problem with Pulseaudio and Blueman, for example. The microphone isn't even registered until I manually change modes for the connection. Another annoying thing is that the mac is so aggressive when connecting to devices over BT. I regularly have to restart stuff because my mac hijacked the connection. It seems to do it even when the lid is closed.
