Because he suffers from MDS and as such can not but complain endlessly about anything which Musk has started. It is an unfortunate affliction for which the only cure seems to be extraction from whatever environment the sufferer inhabits and removal to another environment where there are no other sufferers, then slowly acclimatising to this new environment until the sufferer is again able to consider the person causing the derangement objectively.

It is unfortunate because it totally misses the mark in this instance. SpaceX does have a policy of testing early and testing often which has created quite the number of spectacular 'rapid unscheduled disassembles' but their record with regard to passenger vehicles is thus far unscathed, most likely because they have 'tested Dragon early and often' so as to find failures before the vehicle was put into service.
