Would it actually be helpful? Or are you just baiting to get OP fired?

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.

I think it would be helpful because OP's post smells a lot like sanctimonious grandstanding.

I don’t know if it would be that effective- it’s clear this persons post is currently in the positive. It’s highly likely there are other people in positions where they can hire others who have contributed to keeping the position in the positive score range (or at least not so negative that you have to highlight it to see it). By making it more broad we can assume that a silent chunk of people upvoting it agree for their own companies and positions of power too, and those we can’t pull aside to ask who they work for.

The intention of this post isn't to "hit hard" it's just to remind people who may have forgotten and are in positions of hiring power that there are a lot of people (devs/non-devs) unemployed or furloughed right now through no fault of their own that should be considered before throwing FB employees, who are some of the highest paid in the valley, parachutes.
