Of course they absolutely are. I keep literally all my documents in the cloud. I'm constantly editing my documents from different devices -- my phone, my laptop, my tablet. Users like myself are absolutely asking for cloud connectivity.

If by "cloud" you mean a filesystem-like abstraction that's synchronized across multiple systems (e.g. Dropbox or OneDrive), I have no objection to that. Heck, I even called out Dropbox as a viable alternative to "cloud connectivity". What I am objecting to is the tendency that many apps (especially mobile apps) have of locking your data away in their cloud, making it impossible to get at your data, back it up, or share it with a different application.

Many apps these days are webapps, and absolutely require both interfaces to work.

That's a nonsequitir. It's entirely possible to detect the size and capabilities of the device that user is using and display a UI that's appropriate to that device. What I'm militating against is the lazy approach of designing the UI for mobile first, and then using CSS media queries to scale it up fit a desktop viewport. That results in acres of wasted space and a poor user experience, because the user doesn't have the same interaction expectations that they would have if they were using the UI on a mobile/touch device.

Except WIMP doesn't work on mobile.

And mobile UIs don't work on desktop. Trying to make a one-size-fits-all UI is a fool's errand. Much better to design each UI for the platform that it will be displayed on (laptop, tablet, phone, smartwatch, etc) than trying to scale a single UI across multiple devices.
