Thank you - I was going to do that; probably would not have been so concise.
A video can be way more powerful than a local observer (who may have
skin in the game, possibly a crane company employee?)

If the video is advanced frame-by-frame at about 7 to 8 seconds the jib can be
seen to deflect downwards continuously until failure occurs. If the strap
broke first, the jib reaction prior to failure would have been upwards in the
opposite direction due to the instant release of bending tension. The full
counter-reaction of the boom goes off screen at about 9 seconds as the camera
follows the fall of the tower section, but reappears at 11 to 13 seconds when
reverse curvature of the boom from the counter-reaction is visible through the
first boom oscillation.

Looks like the cable was not attached to the tower properly. I think
I could see the strap around the upper section break.

The video short linked below from HamRadioClubLuzerneCoPA happened to
pop up on my computer today. That installation became very
dangerous. I wonder if anyone knows the details? Hopefully there
were no injuries.
