Even without the pandemic I doubt there was really a market for Quibi. When I watch my paid premium content I'd like to give it my full attention. Waiting in line or commuting are not exactly the kind of times when I'd be able to do that, so if I am on my phone I'll be doing something that doesn't require my full attention.
I watch my paid streaming services at home on my big screen where I can give it my full attention and get the best video and audio quality. But Quibi was so invested in their business model that they would not even give people the option to watch on their big screens at home.
I looked at another Wikipedia article to find out about what happened with Kwesi's foot and found this: "After two months, calluses on the bottoms of feet molt and fall off from lack of use, leaving soft new skin."
