Because the press doesn’t publicize NTSB reports months after the crash. It doesn’t have the same sensational draw to earn clicks. Look up the NTSB docket management system where they release all the reports (just be aware that they list photos as “Text/Image” but videos as “Other”).
It's a recording of a screen playing the video, the hand-held aspect is the amateur getting the footage by pulling out their phone camera and recording a screen...
It looks like the video is taken from https://www.youtube.com/watch?v=VaIL2UOX4ss - it says it's "Kennedy Center Cam", it also wobbles, but that's probably wind. But yeah, it's not an airport camera.
