A safety lesson learned in private and not shared could allow loss of life by another party that did not have access to the safety lesson.
Yes, AWE R&D involves a lot of crashing, as a pioneering aviation field, but should not involve a lot of venture-capitalist cover-up. Investors also deserve to know who is crashing and why. Expect lawsuits by harmed parties from both investment and direct victim classes.
Yes, soft kites are very dangerous if known safety methods are not applied, but high-mass high-velocity rigid aircraft are the greater traditional hazard as reflected in aviation regulations.
A kite-killer mechanism that turns a soft kite into a falling cloth may well be safer than early over-dependence on a rigid aircraft returning autonomously to base.
Multiline topologies are a better fit to soft kite units, due to less tether-drag at lower inherent velocities and other practical issues.
