I used to work for Microsoft on Edge Browser. Our tests ran on a clean version of Windows. Seeing the ads pop up in start menu, MSN homepage on Edge, little squares ads on bing page made me a bit miserable, day by day.
The default experience was garbage thrown in your face.
The leadership had to drive revenue growth and msn/ads were a money maker. That’s how they get promoted and we had to play their game.
Seeing that ladder chasing culture made me quit.
Very few companies actually legit give a shit about their users and the user experience. It’s so easy to blindly do things that annoy users but make a quick buck.
