You run a large, high resolution screen with your browser maximized?
I have a 4k screen. Most of the time I keep my browsers half width. For most sites it seems to be the best use of screen real estate. Even at half width that site's CSS restricts the width of the content too much, leaving a lot of wasted padding on either side.

Probably like 98% of the time, yes.
It's not an ultrawide, just a 27" 16:9 screen.
I find small windows to perform poorly on anything that's not just a simple document (gmail, hacker news, etc) because those require some horizontal space.
