There wasn't a question in my comment. And I'm not sure how much value there is in a generic comment about intellectual property from a professor because the journalist needed a quote for their story.
There's an implicit question, or at least an admission of ignorance.
Do you really think that the idea of patenting "story" wouldn't have come across Snap given that is their main revenue driving feature? Do you think FB should have patented NF back when it was the first one who launched it?
