some things I've noticed: Mobil Safari seems to be using the search bar to hijack my google search (Particularly for locations which open in apple maps)
Although I'm mostly linux these days I went to install an alternative browser on a windows machine (using edge to download). I mentioned this in another post, but edge seems to watch for "chrome" or "firefox" downloads and politely reminds you that 'Edge is a great browser with added "trust of microsoft"' (A company who happen to be watching when you download a web browser).

Linux seems like an OS that is way more respectful.
"Ultimately though, if this experience isn't right for you, you can turn off this feature the first time it launches in Microsoft Edge, and then in Outlook settings at any time after that."
You usually download a browser just once, so turning if off isn't the issue. I suspect some of less technically inclined might abide by it and not download the new broswer.
It almost seems like trial run for stopping the download. I can imagine "clippy" popping up an saying "I see your trying to download a browser, I'm sorry, I can't allow that"
Gmail still nags me about not using Chrome.
I don't see the issue here.
