I feel bad there are no good Crossfit boxes in your area. I train or used to train at one of the best in the country. It took my own training and knowledge to the next level. A far higher level than any bodybuilding forum or globo gym trainer could ever take it. It got me into powerlifting (with proper coaches) and really upped my mobility game. It was the next best thing to joining a Westside Barbell Club...but that's because my Crossfit box also had a Barbell Club, which was what I was a member of.
I guess I can repeat myself, not that it will make any difference, but whenever someone is lifting with bad form - I always see them called out on it, and the coaches where I've been at have always always preached good form and that when form breaks down, reps should stop. I guess not all boxes are created equal.
Some of your points are good, but I strongly agree with the writer of this article below. Crossfit has done a ton of good for the fitness industry.

PS: I just want to also state, that I have never done nor seen high-rep olympic lifts done in Crossfit. I have never seen programming that includes AMRAP Overhead Squats, or 30 OH Squats, or even 20 OH Squats. What I have seen, are many WODs that include a strength portion and a METCON portion. The strength portion does not include high-rep anything. Usually about 5 reps, for sets. Metabolic conditioning workouts typically include lifts like high-rep, lower weight deadlifts combined with something else, in a circuit. I NEVER see olympic lifts as part of the METCON.
