Again, no non mobile OS prevents native applications from using the clipboard as it should be used. And none of them show any signs of changing that.

Are you saying native apps are less well sandboxed than web apps? Because that is exactly what I said. But they are getting there, and that is good.

Nope, native applications are not ever going to get the ridiculous level of sandboxing demonstrated by the restrictions on accessing the clipboard in the article. Nor are they ever going to be prevented from accessing the file system as web applications are.

They are going to on all good systems for very valid reasons, and they are halfway there.
