Adobe Reader DC - File > Share forcing a save

We just moved to Adobe Reader - DC version. When we click on File > Share, we now get prompted to save the file first. This didn't happen in previous versions of Adobe Reader.

At law firms, we save the emails WITH their attachment(s) so we don't need to save the file separately first. That would mean we'd have to save it locally, send it via email, then delete the local copy. Unnecessary steps.

Microsoft Office products don't require saving a file when Emailing it as an attachment. What's the disconnect here?
 
My thought is the SAVE is associated with their Cloud service for global sharing and access.

My question is Why Adobe? I've been using Foxit PhantomPDF and quite pleased with it and lack of the notorious Adobe instability and frequent updates.
