That doesn't make sense, the decisions which lead to the 737 MAX debacles were made well before the now receding wave of corporate DEI efforts. 737 Max was announced in 2011, work (likely) started a few years prior to that. DEI started gaining traction around 2014, really took off in 2020, if you trust google trends.
A Boeing with chutzpah would have committed to a new plane in the last decade. Their real failure was a failure to aim high. Long before DEI.
