Some might argue that web scraping to export data from non-participating services has been normalized for a significant amount of time. This has been a common practice for decades!

Further, it's perhaps possible that copy semantics comprise a very useful operational primitive when coupled with the existing delete primitives. With copy and delete actions available to them, users can choose to share, move, and delete data as they see fit. With only move actions available, users do not get to make their own choices and are limited to the choices prescribed for them.

There is *substantial( merit in calling for more directly useful primitives, but this could perhaps be done in a context that is informed by knowledge of extant primitives.
