By the way, I do not get the problems have with the ASD Webcam. I checked it against two dedicated webcam/soundbar-solutions and was impressed by how easily it beat those 500—800€ peripherals not only with the only really good «center stage» functionality but also ease of use and sound quality. In the end we opted for Camo and an iPhone 13 as webcam, which offers optical zoom and better quality, but for a built-in-webcam I was surprised by how good the ASD looked and just simply worked...
From what I've seen, the main concern is with low-light performance. Even in ideal lighting situations (i.e. including the bright lights of Apple's own sales floor), there is a fair amount of grain/noise.
It's not earth-shattering bad, certainly more than adequate for intended use of remote conferencing etc., but it's also not at all exciting - Especially for a ~$2000 display that is likely to be used for 5-10 years. If the trajectory of remote work continues, in a few years I would imagine 4K webcams to be commonplace/a necessity for professional requirements.
I think the initial criticism was amplified by the fact that it's the same combo of 12 MP lens and A13 Bionic chip found in the iPhone 11, but delivered significantly poorer results. To some extent, firmware updates have made some improvements.
