No one is forcing anything on you. You gave Microsoft permission, to Install updates, new features, etc, when, where, and how they deemed best when you agreed to the terms and conditions at the time you installed Windows 10. The vast majority are quite happy with the new Edge If you want to uninstall Edge the best and easiest way I have found is to download and install Revo Uninstaller. It will remove the new Edge and replace it with Legacy. Just find Edge in your list of Apps and pin to the taskbar.you can get it here: https://www.revouninstaller.com/free-uninstall/
I hope this helps and if you need any further assistance please post and we will be glad to assist you.
