Can people provide some literature/data to show evidence of how BCG (Boston Consulting Group) is connected various incidents of companies demise or other negatively impactful incidences please

As the title suggests I would love to see if others can provide some reading regarding BCG and their less than desirable work that has led to downfall of companies or other work they have done that is morally questionable or downright evil. The reason ask is because I came across a post that links BCG to the recent 'aid' efforts in a conflict (without naming names most people might know what I'm referring to) which have been exposed as having nefarious motives.

Recently the company I work at announced they have employed the services of BCG, so I want to collect some research before I open my mouth at work and demand that we reconsider working with BCG.

Thanks in advance for any and all inputs.
