The 'what is good for the web is good for Google' line certainly was true in 2005 when the greatest threat to the web was companies like microsoft using internet explorer to adjust the de-facto web standards and privatize it in the "EEE" fashion.

Obviously the most visited websites would maintain the web better than OS vendors, their buisness depended on it being open.

We have a similar situation now, but with google locking down the most common browser (Manifest v3) and using extensions of web standards to maintain a dominant position.
