I think one of the things that short form videos do really well is that they punish creators who pad their videos with unnecessary filler content. On TikTok for example (Not necessarily a fan of the app but it's a good example) no videos start with all that empty jabbering you often see on YouTube ("Welcome to my channel...", "Today we will...", "Please Like and Subscribe...", "This video is sponsored by...", etc), because if they tried any of that crap the viewers would just swipe the content away. So, instead they always get straight to the point. That part is really refreshing.

Of course, there are other issues instead.
