Moving to WebKit? Only if you count CyberDog, I guess. Safari was always WebKit based.
Also, your phrasing could be read as if Chrome came before Safari, but Safari is from 2003 (https://en.wikipedia.org/wiki/Safari_version_history), Chrome from 2008 (https://en.wikipedia.org/wiki/Google_Chrome_release_history).

I was around as well. My recollection is that they let it twist in the wind because SaaS competed with their two interdependent quasi-monopolies: Windows and Office.Which is another instance of the Innovator's Dilemma: How can a successful company embrace technology that disrupts themselves?
It wasn't called SaaS back then, but in any case -- they let it "twist in the wind" because their market had become the enterprise, and that's a market that wants stability, predictability and no updates if they can be avoided. By then they had killed all competition, so their incentives were to keep businesses locked-in through backward compatibility and security fixes. Add to that the big move to .Net and an effort to replace Flash...
IMHO it wasn't about the antitrust or platform control (they could have broken all the SaaS apps they wanted with each update, they had 95%+ of the market and were n.1 target for every website out there). They just had other priorities: the browser war had been won and attention was now on the enterprise market. Around that time, IIRC, Gates also retired, leaving Ballmer in charge; Ballmer was not the sort of technologist to lose much sleep over "the future of the web"...
The author is right, the details aren't the same but the same attitude exists. The author is simply speaking up before the differences become extreme.
Microsoft didn't "break the web" they created their own web and then let it twist in the wind because they were pissed about the government beat down.
Apple didn't get their hand slapped, but they did build something so lucrative that evolving Safari became a smaller priority, which some would argue aligns well with their push to the App/closed ecosystem model.
