This question was inspired by my hatred of Temporal Anti-Aliasing which, in many games nowadays, is poorly used as a performance bandaid. On lower resolutions it will smudge and blur the image and certain bad cases of TAA will cause visible ghosting.
Yet in spite of all this, certain games won’t let you turn it off or have hair/fur/foliage look like dogshit without it so sometimes I still use it.
I work in marketing and it legitimately has no downside to a business other than having one team to make sure it works and the other to make it look good. It makes sense to not have to pay Google or Adobe or whatever other tech company that charges for web usage and ad tracking. At the same time, it allows companies a direct connection to you through push notifications.
