I’ll never understand how Twitch became as big as a thing as it is.
You already answered that in your comment.
You want to watch videos, not livestreams. Of course a video will be better at being, you know, a video (nicely edited, in short format, etc). A livestream is different for many reasons, none of which interests you apparently.
Nothing wrong with that tbh. It’s just not for you.
Same, I’d take it any day over VLC because of native dark mode. VLC’s themes are janky and weird-looking.
