AITA for breaking basketball court's tradition in my neighborhood

There's this thing on the park where a few guys drop bright orange cones and then leave for coffee or something. After two weekends of watching an empty court sit under plastic cones while the posted sign says no reserving courts, I realized it was just a tradition they invented.

At 7:59 I picked up the four orange cones sitting at midcourt and dropped them in the rec bin by the fence. I saw ten players were already on the asphalt stretching and dribbling. The sign on the gate says courts open at 8 and can’t be reserved. We checked in, matched five a side, and tipped off to eleven. A dad with his kid slid onto the sideline and nodded. It felt like the simplest way to start. people present play, others wait. The cone crew returned a few minutes after eight. Confusion flashed, then anger. They talked about tradition and said the cones keep things organized. Phones came out. I pointed to the posted rules and kept the game moving. We finished the run. They took the next game. The air stayed tight, but the rotation worked and everyone got on the floor. If a public space needs order, it should come from the posted rules or a staffer, not whoever drops cones at dawn.
