I’m not saying we shouldn’t criticize Facebook, or that they shouldn’t be the ones to solve this problem. But I think it’s important to frame it as a problem to be solved instead of growing extremely cynical and saying Facebook is pure evil.
When Facebook says they don't know something there are a few possibilities, the least likely is that they don't know and don't have a reason not to find out.
I do agree with you that it is not up to them to fix. They should be limited to whatever extent possible in what research they can do on their own discretion to prevent them from staying ahead of public information and misleading research.
since we've already conceded that votes can be simply bought through advertising, the whole thing was already looking pretty sketchy.
its kind of pointless to rail at the parasites feeding off the open wounds.
