How is this different from automatic updates or virus scans?
The diff is you install the virus scanner which then does DLs on your behalf hopefully from a trusted source. The install/remove asset can be done by anyone it seems which may or may not be connected w/ the purpose of the app initially loaded. You DL an app which then does install/remove asset of who knows what. Also it seems google has the machinery to do mass or focused install/remove asset. I suspect, as someone already said, the govt could use this feature to DL ‘things’ to a persons phone. It could be used for good or bad depending on the goals of the agency involved.
