It's a choice to fly your airplane across the land/takeoff trajectory for a major airport. They also essentially flew by the F1 track on the way.
No, it isn't. It's a small non-jet aircraft. https://en.wikipedia.org/wiki/Cessna_182_Skylane

They are not required to in that airspace at that altitude.
No, it isn't. You can get a Cessna for less than a Cybertruck. You cannot get a private jet that cheap.
> If you're flying a couple miles away from a commercial airport and across the path of the runways, maybe you're not required to be listening to ATC, but that's definitely a choice you're making to risk it.
There's an explicit system of controlled airspace around airports.

The Cessna was operating in airspace it had the legal right to be in and no need for ATC coordination. Near some of the busiest airports, etiquitte requires you try not to make a nuisance of yourself as a GA pilot to ATC.
