So how come SpaceX employees don't revolt over the use of their rockets for military payloads?

Elon Musk is literally out there launching a satellite surveillance network to help the military spy on the entire planet, meanwhile Microsoft employees are getting hung up on a headset that will maybe improve their aim, or maybe lead to fewer deaths in the field.

Besides that, was there ever a time where Microsoft wasn't selling their services to the U.S. military? It's hard to resist a contract from the world's largest employer.
