Turnover not takeover
These happen everyday and not just in the US, they're mostly separation issues due to various sized aircraft getting too close and becoming at risk of wake turbulence,I follow those ATC youtube channels and there's been a separation incident in the US every few months, for almost 2-3 years now. Many at SF and DC.
But unlike this one, none involved a helicopter, most involved an aircraft on the runway in conflict with one in the air or on a taxiway, in many, the ATC seemed to be at fault, and of course, for the ones in the air, TCAS got involved.
