Yup, raise any flags and risk being treated as an outsider/treated poorly. That's my current situation after raising concerns ranging from being way overcharged on a government client project by a vendor who happens to be friends with a manager, and catching a now ex manager pulling mitm attacks on a router (to snoop/play politics) which happens to be on the same network as servers housing client data. It's an awful feeling not being able to have glaring issues resolved or be treated like shit after doing what seemed right and in the best interest of the company.

Needless to say, I'm making moves to get the hell out of there
