Not great if you like their product as a consumer, but 1Password's biggest feature differentiator right now is better family sharing than iOS provides. That could easily change in a future iOS version, and then it's suddenly a lot harder for 1Password to grow by selling a $60/year password manager subscription.
Enterprise features on the other hand, that's not something that OS vendors are likely to ship.
While I don't like the newer versions of Dropbox as much as the old ones, I can understand how pressure from iCloud and OneDrive pushed them toward enterprise features over consumer users.
Maybe not on Mac, but MS will probably try.
Unlike many _other_ product companies, they all dogwood their own code. Also, IIRC all members of a team account are given a family account for their own use (you’d obviously have to convert if you separate from the company), so they are building for _people_.
This may have overlapped with when Guido was working there, though they may have built those clients before he joined, of course.
It doesn't bode well for the future direction of what has up to now been a good consumer-focused product.
Like how Dropbox has gone from "a folder that synchronizes your files" to "an electron app for having discussion threads about files" because that's what business customers want.
