It is better not to crash foil kites hard like in FS video. Even if kite doesn't necessarily explode (which leads laborious repair job because ribs and straps tear) pressure damages seams causing them to leak.
Couple of years ago I was asked to check/tune Speed4 dlx kite, it was used as a snow kite for two seasons by a beginner. I later saw how he did with his kites and it was quite harsh Fabrics of that kite were not worn out but every seam was loosened and leaked air. There was a torn rib or two which I repaired (at this point I didn't realize the problem with the seams).
Bridle and mixer were also badly out of tune but they were fixable. Seams not so much. I couldn't see any other reason for damage than pressure shocks from numerous hard crashes kite had suffered.
