Your first point seems to be reflected in the article, except that, if they are correct, the high end of Class D amplifiers apparently is not "super cheap".

I don't quite get the aggressiveness of your second point: surely just leaving whatever your first association to a topic is out cannot warrant such outrage? It's not like they present this article as groundbreaking innovation. Not only do they cite other DIY efforts. The whole premise of the article is that the author himself already did this ten years ago,.

It comes more down to the design of the board and the quality of the other components on the board. The TPA3250 he mentions is quite a new chip, but if you look on Aliexpress for an older chip like the TPA3116 there is literally thousands of examples: https://www.aliexpress.com/wholesale?catId=0&initiative_id=S...

I imagine this guy must have found the components of a site similar to DIY Audio. It would have been a nice addition to steer people in the direction of more information if they are interested in the topic (which a lot of the comments here seem to be asking about).
