Tbh I don’t get this. I know some ppl hate thumbnails typical “style” but this doesn’t improve anything imo. Between the video title autoplay of keyframes of the video (unless you clearly can see it’s autoplay of a freaking sponsor spot) and the description of the video are more useful for finding out whether it’s worth watching then I’ve ever found a thumbnail to be even when they weren’t like they are now.
