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.
Check out piped.video. It’s content of youtube without youtube. That means no recommendatios based on their algorythm, which might be nice sometimes but it’s a good alternative. LibreTube for an Android app is what I use.
Ente seems good Google Photos alternative, but you do have to pay for it (they have like 1GB free space)
Yeah I use SmartTube on my TV and piped on my phone but I still count that as “using YouTube.”
