To understand it just look at the complaints of tech workers. The majority of them consider internal actions as grossly more important than any outside effects. Thus, if the hiring policy is progressive and if they have good HR, and a happy working life and if the managers don't trip up with certain internal political issues this far outstrips any negative actual real world effects. Walk outs of employees happen due to internal drama, not any external actions. Twitter therefore is a great, comfortable, safe and inclusive place to work even if history might prove it to be more damaging to mental health and physical security of the world than Google.

Now, the new tech unions that are occurring in a few companies give some hope against this hypocrisy as they all seem to have a line or two in their mission statements which speak up about shaping the direction and action of their employers. I hope they live up to their promise.
