Engineers at Facebook make $100k+ a year and have absolutely no standing to shirk moral responsibility. By all means they should be called out. More effective than deflecting to some vague unaccountable company policy.
By that description, anyone working for Google, Amazon, Microsoft are inherently immoral. If you are willing to cast a large net for your own grievances then you should demonize the rest, as those companies do things that you might not find particularly important but others find "immoral".
They are and our community sees Facebook, Google, Amazon and Microsoft as generally committing many of the same sins. We are not charitable in our views of them or their employees. You can tell by the comments on Hacker News.
