I'm not sure what kind of training background you come from, but many of the exercises you mentioned are core parts of training programs for competitive athletes in a number of sports. High rep oly movements = dumb? In what situation? With what intended training effect? Rep/weight schemes, in a periodized training program for an athlete are set to achieve a specific training goals. In one phase of the program that may be power endurance, for example. In a training program for competitive rowers high rep (30+) sets of power cleans at a low weight may be used to build power endurance. Deadlifting 65% of 1RM for max reps is another very common exercise prescription for athletes building power endurance. If the exercise is stopped when form breaks down, I see nothing wrong here. 65% is a relatively light load. If you have a decent deadlift it's only about 300 lbs or so - a good athlete will have no trouble keep form for sets of 10+. The desired training effect of a high rep 65% effort is much different than a 85-100% max strength effort, or even a 65% low rep, speed focus. High rep box jumps, for untrained individuals = a bad idea. If you've built up to it and have no achilles issues, this is not a concern.

In all situations. This is never a good idea. Ever. > With what intended training effect? If it's to improve technique, do more sets.

I'll say it again: quality control and exercise selection. > If you've built up to it and have no achilles issues, this is not a concern. And yet I see middle-aged housewives doing AMRAPs on box jumps. And it's not just repetitive strain injuries. Misjudge the jump (because, I dunno, you're really tired from high rep box jumping), land on toes, fall down, snap. A lot of Crossfit is fine. The problems still remain that quality control is explicitly non-existent and that exercise selection is hit-and-miss with a genuine fondness for stupid ideas. Basically, no good and safe Crossfit gym has any resemblance to Crossfit HQ's vision except to pay a licensing fee to use the trademark.
