Office 365 "The fine print" popup message - is it legitimate?

I received the "Fine Print" dialog this afternoon as well.  I have an Office 365 Account for home.  But the "Fine Print" dialog appeared on a machine at my work place running Office 2016 (without Office 365).  Our Corporate IT is not aware of any changes to our licensing.  We are somewhat reticent to simply agree to a "Fine Print" dialog without any details on how and why licensing suddenly changed.  This kind of thing is at least unethical.

hi,  for some reason my original reply was marked as spam and removed?  

to recap, I noticed that the popup license text says 'last update September 2017';  the popup displayed when launching Visio Pro 2016 only mentions Visio and not the Office suite.

and, a search for similar scenarios found a few similar instances.

Not sure how that's considered spam.  :)

hi,  I noticed that the popup license agreement text says 'last updated September 2017'.

And, the 'fine print' popup displayed when launching Visio Pro 2016 only references Visio, and not the entire suite of Office apps.

Apparently, similar scenarios have occurred in the past;  this is just one example that showed up in search results with a last edited date in 2018:  https://support.microsoft.com/en-us/help/884202/you-must-accept-the-office-end-user-license-agreement-every-time-that

And, I only noticed the popup late yesterday.

I'm also being a bit cautious, though that might change shortly, as I use Office daily, and alternatives won't meet my req'ts.
