I have no idea whether OP would be fired if they mention where they work. While through context I'd infer that they're interviewing people on behalf of an established tech company, it's also possible that they're running a small consulting business or something, such that publicly commenting on controversial topics wouldn't affect their relationship with their employer.

Either way, saying that FB is bad and their devs are immoral and you would prefer not to hire them because they demonstrate their lack of backbone by not standing up to Zuck is a pretty ironic thing to be posting anonymously.
