It's not necessarily consultants in these companies that are malicious. I find working with many to be honest, and deeply caring about their work. It's that some of the management in these companies are incentivized to engage in duplicitous behavior to gain clients one way or another.

Working for a tech consultancy before, they do have clear lines to distinguish for legal reasons and make you take courses. For e.g., you can't give or receive gifts of any monetary value, etc. But management find other ways, to gain client's trust and affection. One way is to overwork the consultants, and other is to share information that is privy sometimes.
