I'm not making any claim at all about "most people".
I'm saying that iCloud isn't properly encrypted, which for some people and organisations will be a problem, and that it is then a greater problem for those people and organisations that it is unusually difficult to transfer data between iOS devices and other systems through other means because of the inhibiting choices that Apple has made.
It's much like the argument that the default behaviour for consumer software should normally be to install security updates automatically, but installation of updates should still be configurable for those who do know what they're doing and need more control over their systems.
If you’re part of an organization where security is important, you would force all of your employees to register with your MDM solution and prohibit any iCloud backups, you would probably have them using Office for iOS and tell them to save their files to OneDrive for Business and enable encryption.
I doubt many businesses are using iWorks with iCloud.
