Author here, yes, this is indeed the point of the article. Desktop operating systems could/should have implemented such a feature a long time ago, it is clearly a security "blind spot" at the moment.
What's the point of copy notification if apps can just read all your emails and steal all your files anyway.
Android and iOS both have this feature already. That's the best we can do for now.
Not very appealing. It only works on mobile because there wasn't an existing industry used to 2% fees and unrestricted APIs.
Unsurprisingly Microsoft has abandoned app store fees and mandatory sandboxing so their app store has any chance of being used. Not sure about Apple.
We are discussing "paste" notifications. Knowing that an "app" is constantly pasting(fetching) the contents of the clipboard seems suspicious behavior and I as a user would like to be made aware of it.
