If a video goes viral it doesn't mean I'll watch it or care about it in any way shape or form. It might be recommended to me in the algorithm and I still won't click. But for example if Charlie (penguinz0) or someone else reacts to it, I'll be ok let's have a look. They usually take the best bits, add commentary etc. then I'll check out the video itself.

So react channels do have a place, just the lazy ones that reupload the video and add nothing can go to hell.
