It has surprised me how hard it has been to find a protein powder that isn't sweetened. Usually by stevia, nowadays.
By far the thing with the most sugar added that I was late to give up, is a standard yogurt. Tried making our own vanilla yogurt, once. I don't think we succeeded at making it as sweet as what we went in expecting. Despite an absurd amount of sugar added in.

The yogurt Nazi in me feels compelled to point out that standard yogurt has no added sugars, and is offended that someone conflates that with vanilla yogurt. :-)
Reminds me of twenty years ago where stores routinely sold yogurt makers. Except they didn't make yogurt. They made frozen yogurt. You needed yogurt as an ingredient. Face palm.
Plain yogurt - without gelarin, pectin and sugars - is really awesome food. People should try it! Really easy to make at home as well with an instant pot.
And yes. Plain yogurt is sour. It hasn't gone bad.
The single serve packages are "ready to eat" for people that want a sweetened snack.
May be the case right now, but when I lived in the Midwest 15+ years ago, the regular grocery stores (Meijer, etc) would carry only ones that had gelatin or pectin. I'd have to go to the fancier (e.g. organic/natural) stores to find brands like Nancy's or Mountain High - and they'd be very pricey.
The West coast always had brands like Nancy's in regular stores (at normal prices).
Perhaps now one can easily find regular plain yogurt without additives in those places.

The various 'Greek' varieties are also widely available and tend not to use thickeners.
Also, I'm not sure why we would discount "right now".
You are correct, other yogurts are all deserts in the us. I was sorely dissapointed in chobani. When I'm eating yogurt I'm usually doing fage or goatgurt and frozen berry mix.
