I'd seriously doubt more than a few of people at Google would want to use 365 at work. I for one never felt the need when I was there nor afterwards and the entire company is fully utilizing Google Docs which is a better product as far as sharing and search is concerned. It's not like people at Google constantly email .docx files to each other, lol. Nevertheless, you can request it (in an AppStore like fashion, not some overburdened process) if you really need MSOffice, but Zoom binary being banned seems to be a completely different matter though, as pointed out in other posts.
For workplace collaboration, sharing is the highlight, not formatting (unless you're designing for paper-based publication). I have to say the few times I encountered the browser-based Word 356, it felt like total shit. Cannot imagine anyone really using it if they have the desktop app installed. Seems like a checkmark product and the real users end up using the full app version. I've even heard this from friends at Microsoft.
From what I've tried the desktop apps themselves do cloud-driven collab just fine, so I don't really see a reason to use a browser app when native's available. May just be me seeing things, but the native-to-native sync seems faster than with the web apps. Sadly that means sharing is a bit less convenient than just click link to open.
