Still plenty of evil things you can do without admin privileges, like running a server in the background that launches Zoom (as they tried previously).

The installer has to ask too though, doesn't it? So using an installer still provides no benefit.

Yes, but the point is that most Mac apps should need neither installer nor admin privileges.

I believe that (when I wrote and installer for internal use while at Apple) it needn't require admin to drop an app in, say, ~/Applications.
