Cleartext HTTP is blocked for users on Microsoft Edge with "Automatically switch to more secure connections with Automatic HTTPS" turned on via corporate policy - which means they can't turn it off to get around the "feature".

There's also this chrome extension which can be configured by Corporate IT to disable HTTP and then they can also prevent disabling the extension.

On Edge: https://blogs.windows.com/wp-content/uploads/prod/sites/33/2... shows an option “Try http://http.badssl.com/”; does that not work, or have things changed since that time? (https://www.eff.org/files/2021/09/21/edge_https_only.gif also shows this, in the strictest Automatic HTTPS mode.)
