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.
