Many of the storm chasers who post videos aren't getting information of value, they're looking for clicks. Here in Kansas there was a problem with these folks in one area of the state. They were blocking roads and interfering with first responder access.
From what I gather, the amateurs (not to be confused with people doing research) are creating concerns for the safety of the people who live in the area and themselves. Many of them are ignorant of the peripheral hazards (e.g. extremely large hail) and risk becoming victims themselves.
It's always problematic enough after a storm dealing with legitimate news reporters. In a confusing (and frequently dangerous) situation, victims don't deserve having emergency response impeded because there's a group of thrill seekers getting in the way.
My guess is that others are aware of disaster response that has been delayed by the curious (hurricane, earthquake, wildfire, flood). The problem with tornadoes is that they are short term events and it's become fashionable to try to find them on the ground.
