It was clearaly parody but at a minimum parts of it depart from parody and into pure trolling such as "Because I’m a fucking self-contradictory hypocrite!"

Overall it is a continuation of an effort of some members of the community to attack others in a hostile and divisive manner which is harmful not helpful.

Am I to understand that if I remove that sentence, you would remove your flag?

You could try reading my entire comment.

censoring insults is legitimate, censoring satire is not. not even in the real world.
when the powerful can censor the minnow criticizing them this is censorship of the worst type.
flagging something because you simply don't believe it is helpful it is not in accordance with the flagging etiquette, especially when your flagging means censorship.

I did not flag it because of satire, nor criticism, nor because I simply don't believe it is helpful. I downvoted because it departs from satire into pure trolling and because I believe it is harmful (the latter being a recommended reason for doing so in the white paper and repeatedly practiced by the developers themselves).

I thought it's a real interview before reading.. I feel I'm played. Flag or not?

It's pretty obvious when you get to a point that it is a parody. It would not be as funny if it were declared in the beginning of the post and seemed pointless to declare it at the end. You were supposed to realise half way through, it's part of the parody. If you did not enjoy that aspect I understand. If you were offended by it, I understand.
