It could have passed as a troll question given that this is an old an well-known problem, but I guess it's best to err on the side of informing people than turning them away.
I feel strongly that we’re at the point where one can’t think of Facebook and be ignorant of the problems and the clear abusive practices they have and continue to be engaged in. Every time they get caught they feint an apology and proceed to either ignore the issue, continue that same practice but in a different way, or engage in some new abusive scheme. It is foundational to them because it is fundamentally part of Mark Zuckerberg’s ethics, or lack there of as the case appears to be.
So... in my opinion anyone going to work for Facebook, or continuing to work for them is no different than someone doing the same at a tobacco company. They know what is going on at those organizations and they are choosing to look the other way. That in and of itself is not illegal, of course, but they can’t cry foul when they get accused of doing immoral and unethical things while employed there.
Can you explain (with links please) how Facebook are ethically equivalent to tobacco companies (who's product literally (not figuratively) kills people).
If you can't, then I'm going to assume that it's mindless hyperbole (a straight to which Facebook, for whatever reason, appears to be prone to).
They are expressing their own opinion, and the comment clearly explains how they draw a parallel between Facebook and tobacco companies. Why do you need a link?
Also, while Facebook may not directly kill people, the hate speech that it helps proliferate does have real consequences for real people. One such instance was in the Muslim genocide in Myanmar. Since you appear to like links a lot, here is one for you:
