"Quietly" in the title is an AI slopspam pattern. It's an over-used teenager hyperbolic crutch word on par with "literally", "actually", "honestly" and similar.

Sometimes it's use is appropriate, but not in this case. Microsoft announced this change loudly, multiple times, starting more than a year ago. I seem to recall one of those announcements being discussed here on HN. Even the article links to it's own previous announcements, so "quietly" here is stupid rage bait to justify a blogspam advert.
