These are managed and controlled events. They would have setup dedicated wifi systems to eliminate as much interference as possible. I’ve worked at a couple of small scale public events for companies … they manage things down to the smallest details to try to make sure things work as intended. The bigger the company, the bigger the budget and the more they try to control everything.

For a company like Facebook hosting a public event like this, they would have controlled absolutely everything, including the wifi … and the only variable that they couldn’t control was the AI and what it would, or not do.
