It is intellectually dishonest to call the military-industrial complex merely "customers that some Google employees didn't like".
Humans are more than their companies' mission, and your freedom to exercise your political views on how companies should be run inherently relies on this principle, too. So your argument is fundamentally a hypocrites projection.
Besides, many of the Google employees who are against defense projects are against them because those projects actively target their home countries. Much harder problem to fix!
I'm not sure if you're being sarcastic or not. Obviously you don't get to ignore your morals and values just because you're currently employed by someone?
