OP let it go.
Worry about yourself, and let others live their own life.
The plane isn't even at the same airport as you.
Go fly around, enjoy the views, and let other pilots do the same.
Besides, it could backfire on you, and in the end you make enemies, and also get investigated.
I'll tell you a short story.
A good friend of mine lives on a nice dead end country road, everyone has an acreage, and there are only 12 houses on the entire road, 6 on each side.
This was a great road to live on, and for many years everyone got along well. Well 1 place went up for sale, and a woman bought it, she was warmly welcomed to the neighborhood, and they all went on about their lives as they had for years. Soon police cars were seen driving the road regularly , and a cop car had never been seen on that road before. Hmmm then police were stopping at houses and talking about the reports made, and telling people that they better stop breaking laws, or else. It wasn't hard to figure out who was calling the cops, and suddenly her neighbors were not friendly to her, and she wondered why. Her driveway was no longer plowed after a snowstorm by the nice retired man who did all 12 driveways on the road, and the road itself with his huge blower on a tractor. She asked someone to watch her dog and place when going on vacation and was told NO. A guy got tired of her dog in his yard crapping on his lawn and reported the dog regularly, and finally he had enough and shot the dog. The road had an annual bbq get together and she wasn't invited, and she wanted to be. Her car needed a jump start one day, and Nobody would help her. The street was now 11 houses of friends, and 1 enemy. All she had to do was be nice, and mind her own business. Instead she ruffled feathers and ****ed off the neighbors .
Don't be that person!
