Perhaps he knows the subject but he has an interesting (and I'd agree with you, self-serving) spin on history.
For example, "First cost cut: digital filtering (oversampling). That allowed manufacturers to throw out the analog brick wall filter, which was wwayyyyy cheaper" could be stated differently.
Oversampling was done because the early brick wall filters rang like a bell on transients.
When I bought my first CD player in the spring of 1984, there were two main options: Sony (using brick wall filter) or Philips (using oversampling and a more gently-sloped filter).
The reviews of the Sony consistently knocked it for the ringing in its output, ringing that simply was not present in the Philips CD players. That's one of the reasons why Meridan's first CD player in the 1980's was based upon the Philips transport and digital electronics, and Meridan substituted their analog electronics.
Even the "better" brick wall filters used in the mastering process rang. I have quite a few early CDs where the ringing on transients is so pronounced that it reduces my enjoyment of the music.
Oversampling allowed for more gently sloped (and non-ringing) analog filters initially.
[edit: add the following] Additionally, at the time, oversampling was more expensive than brick wall filters (which is why many manufacturers used brick wall filters in the first place). The digital electronics needed to process the higher frequency digital signal required by oversampling was bleeding-edge for audio equipment in the early 1980's.
