If you get in a car accident, no one counts your car as a victim. This is the same thing.
If you steal from a corporate-owned store, is that a victimless crime?
A corporation is owned by people. It is not "made of" people like some grotesque colossus.
People got shot and HN commenters are using it as a platform to criticize content policies of the company they work for. That is the pertinent thing here. Semantic quibbles about which specific entities count as the “victims” are not terribly relevant.
