I don't think I move the goalpost when I pick up from your example.

I simply do not agree that Facebook can sensibly be responsible here. No, the misdeeds lie with those that use the platform for their personal quarrels.

A recommendation algorithm does not make you a partner in crime. If we talk about guilt, we need to talk about the advertising industry as a whole that doesn't only include Facebook.

Your argument is analogous to rock music making kids more violent without there being a direct causal link. Without that is remains speculation and even statements that they are "a bit guilty" have to be rejected.

That the advertising industry as a whole is detrimental is likely true, but then Facebook taking part of genocide should not be a starter.

I never said Facebook took part in genocide. That was a different commenter. I said Meta aren't an entirely innocent party

That is pure semantics. No, they are not a guilty party. And if they are really at fault it recently was about removing too much content, which they correctly self identified being a problem. So they have at least that.
