Using a different browser on google.com or youtube.com has many times shown me ads claiming that the web is better using Chrome.
Google Cloud's console frequently breaks for non-Chrome users.
YouTube for many years used a non-standard API which only Chrome optimized instead of the standard one which all three implemented, which meant that video playback used far more CPU on other browsers.
YouTube for many years favored WebM format at the expense of video quality and performance.
Google Meet for years would drop sessions for Firefox or Safari. No other WebRTC service had problems with those browsers.
> Chrome's market share destroys every Webkit-based browser combined.
Yes, that's the point. Chrome would not have gotten so far ahead of Firefox and WebKit without both a huge financial push and heavy promotion on Google's most popular web properties.
