It's not just PowerPoint, but other Microsoft products too. Their browser (Edge) is known for being on constant phone home, close doesn't really mean close, self-update without user interaction, odd settings that cause privacy problems, after it updates itself makes changes to settings without user permissions or breaking various security-related extensions, etc... It's a pattern of general disrespect for user privacy and exploitation of unaware users for corporate and 3rd party entity benefit. Look no further than Microsoft's Copilot, which is in the spotlight, and arguably has no respect for users copyright. That PowerPoint (and other Office products) are phoning home users data, should be of no surprise whatsoever.
