When a link to a folder that's shared from the contextual menu on macOS is viewed in the browser by somebody who does not have an account with Dropbox, folders and files are not displayed in list view, so (a) file names are trunkated and (b) more scrolling is to do.
To combat those 2 disadvantages it would be an idea to have list view as default. Then less scrolling would have to be done and the file names are better to read because more characters would display.
The average user may not see the (a) very little and (b) quite pale list view option icon which is (c) placed far away, top right.
