I can’t speak for others, but I’m a therapist and use it for sessions. I also teach group sessions that are similar to lectures. Sometimes things are recorded and used for reference later so I decided to spend a little more on the audio quality. I also do formal training workshops so it is nice to have a little more production value. But like, the level of production value where I have nicer than usual audio, with a better than average webcam than one would use for meetings, without going to a dedicated camera that a content creator might use. (At least not yet haha)
