The only (good/interesting) thing Quibi was doing that no one else was doing was the switchable view thing.
All the other things they tried were foolish and self-defeating: mobile-only (can't watch on my laptop or TV, which makes it harder to watch with a friend), no screenshots (no sharing/memes to promote conversation about the app or content), etc.
There is an ocean of short-form content creators on YouTube, many of them quite talented, who are increasingly desperate for some kind of alternative platform. It would've been so much cheaper and more effective to scoop up a handful of the better ones to create exclusives than to bank the farm on the waning star-power of establishment Hollywood folk. I don't really understand who the target audience is supposed to be.
I feel bad for the handful of decent shows (there must be a few right?) that are stuck on this weird patronizing-feeling platform. "I, just like you fellow kids, enjoy Music-Band and short-form video content on the Cell-Phone, and Celebrities!" platform.
Quibi was interesting bec it was trying to be something that no one else was doing, that requires more than an s3 bucket behind a Netflix clone.
