Providers like MS at least should have figured out that the hypothetical ability to take your data "to go" is important, but nothing they need to worry about being actually used too much, especially in businesses.

One is the anxiety over screwing up and losing your data when you solely manage it. So huge pressure to use "a" reputable company as a steward of the data.

Another is that the user and the spend are disconnected in business scenarios. If attaching a 'cloud' document to something in the app is two clicks, but 4 clicks to do the same from desktop, then the users will want to just stick to the cloud to save them a few clicks at least. They will demand their IT provide microsoft solutions and the IT will shrug and say "well, everyone gets microsoft solutions". Back in the day my company tried to split the difference by purchasing perpetual licenses only for every third edition. Now Microsoft has made that just not viable so you either just pay for as long as you use it or you go elsewhere.

It's also why I don't think any of the providers are actually trying to screw up desktop component prices for fear of local models ruining their day. The tech market has shown they actively jump at the chance to surrender their flexibility to providers, no need to worry about them suddenly deciding to in-house things.
