This is a bunch of gatekeeping with “yeah, they save lives, but might cause harm”. Has anyone actually done analysis to determine if a bunch of amateurs is actually a net negative?
Search and rescue people get upset by these people not following authority, but that’s a standard response anytime amateurs show up to something. It’s the same dilemma of allowing regular people to serve food to large groups. Sure, discourage it if there is enough actual food to serve the survivors, but you sure as hell shouldn’t be doing it when the alternative is starvation.
The same applies when you have dudes like this pilot who was flying where nobody else was. The people out there had 0% chance of rescue without him. Grounding “the cowboy” is just an authority flex.
