Quibi claimed to be competing with free and i think thats where they made their mistake. People on Youtube can leave a 10 minute vlog half way and still feel satisfied that they got their fill of quick stimulation. Quibi forces high effort engagement into a snippet of time where that's the last thing you want to be doing. Of course if they aren't competing with free, then they're competing with Netflix and honestly there is no USP on that side either. Its clear that they were exposed on both sides from the get go.
