Noticed this this morning too. It's bad enough that everything is called CoPilot now, I guess every webpage should also be running it.
The old front-page had actual functions, with recent documents I've seen staff use as part of their normal workflow. But I guess it's important to be "innovative" (we've not tried it before. Because it's dumb) and "disruptive".
And still, it'll always be Office 365.
