McK alum here. Article is drawing conclusions on 6,000 ppl based on allegations of actions of a few. Client confidentiality reigns supreme within the culture, though no cultural is monolithic. Stuff always slips through.

For example, consultants at McK are labeled as 'conflicted' if they have served a competitor of a client in a given industry. Therefore, no consultant at the firm can serve competing firms. And the firm's institutional knowledge which gets carried over is stuff you can read in HBR/McK Quarterly.

Can't excuse blatant securities fraud, but to paint the entire industry with such a brush is slightly sensationalist.
