When Obama did what? Nothing here even remotely resembles the methods used by Obama's campaign.
"No, Obama Didn’t Employ the Same Strategies as Cambridge Analytica"

HN is so full of already-debunked right-wing talking points, it has to stop. This place is full of as much disinformation as anywhere else. Everything in your post is a straight lie, a specific intent to deceive readers and create a false narrative about balance.
Edit: Dang, the flamebait here is the lie, disinformation and chaos created in the statement "When Obama did it, no one cared" which I was responding to. The cause of the flamebait frequently on HN is the frequently-upvoted lies and falsehoods, not my responses. My responses are entirely factual and do not contain lies or disinformation, unlike the flamebait I was responding to. I'm not allowed to reply to you directly because your software won't let me.
