It should perhaps be generalized as "employees usually match the general consensus of their peer-group". Before everyone considered Meta to be ersatz drug dealers, they'd report that they feel what everyone feels.
Google was "do no evil" until they had to choose between that and making the money. The culture has to be not only professed but tested.
Depending on what part of Google you work for, you can absolutely feel good about what you do. The vast majority of employees don't work on ads or adjacent areas. I've never seen another company actually care for non profit related externalities so much. People talk about it like it's the same as Haliburton or Oracle and that's not true.
