> Do they really expect people who go through the effort of installing a third party browser and setting it as default to switch back to Edge because of the grand experience they had with it when Windows opened some help article in it?

A lot of people don't understand what different browsers are, for them there is just "the Internet". I can tell my parents to just install and use Firefox. But they will then happily use a random Edge screen that was last visible to do their next search and be none the wiser. Meanwhile Microsoft will be raking in all their user data and advertisement space.
