To be fair, the one that happened at JFK isn't looking like it was ATCs fault, but rather a possible pilot deviation. Maybe ATC could have caught it earlier? I don' think a report has been produced yet. But in general there is some concern in the industry due to the COVID induced reduced number of flights in the last years, which led to less "day to day work/practice" for both ATC and crew. Simulator trainings don't always necessarily cut it.
