To me, the big mistake both make is in the presumption the UI and utilities shipped with those platforms are why people use it. But no. Nobody uses MacOS because of its nifty calculator or the Finder. It’s the overall toolkit integration with apps. Not even look and feel. But consistency in use.
That view bug has been sitting around since 2009, from what I can gather. But a file manager giving false filesystem state to a user is a showstopper. It violates the main purpose of the program. And risks data loss. Users may make errors based on false information.
Batch renaming I use regularly by ingesting media from cameras, though typically at the command line.
I don’t presume to know why others choose to use anything. But MacOS is highly consistent across apps. Dialog boxes, text input forms, file browsing, hot keys, all the same across applications.
