They stopped promoting “Office” brand when they saw success with Microsoft 365 and dropped Office 365. This was quite some time ago. Now they have just renamed an “app” called “Office” which was like a homescreen for Microsoft 365. I doubt anyone really used it and no one on lemmy seems to even recognize it.
Microsoft 365 bundles other products too like Windows and online Exchange. Guess it was confusing to have both office only and office plus others, and hence they dropped the office only.
