This statement is pure damage control bullshit and the tell tale sign is the unnecessary emphasis and qualification of "the start of mass production". They would have known yields were terrible from pre-production runs. It's entirely possible they had planned/intended to increase production to 15 million but determined they couldn't before any tangible action was taken. They're being forced to stick with their original target, and thus technically and literally are not cutting production by 4 million. The end result however is still a net loss of 4 million units. The ways we reached this same outcome are seemingly contradictory polar opposites, Corporate Double Speak 101. A real denial of this story would have explicitly refuted any plans of a 15 million target or yield issues. This made investors nervous, tanked their stock price, and made potential customers panicked and angry, they had every reason to squash it by any means necessary.
