People use each other's employers to beat each other into submission. When that PyCon 2013 shitstorm went down, the Righteous Male Anger crew were very vocal about their plans to end all their business relationships with SendGrid in retaliation for Adria Richard's actions. It was a calculated move intended to get her fired for what she did. Presumably the dude who got canned for his remarks earlier in that sorry saga was the victim of similar pressure from her supporters.

Sometimes this happens because people force it to happen.
