It would be sort of funny if you included copy/pasted comments from HN in your PR-cleanup post.

They are calling you out for plagiarism because your company is a plagiarist. It's just as clear as seeing a person who is burning and telling them that they are on fire, or a person who is dead and calling them deceased. You do not have the right to lift entire articles from other's sites, even if you DO give attribution.

If you as CEO have so little common sense that you don't even know what plagiarism is, then you need to step down quickly before you open your company up to lawsuits against people who actuallY DO have the money and the time to pursue a suit.

Citing sources does not protect you from plagiarism. That is what I mean by the second version is not okay. If the lesson you're learning here is "I just need to make sure we link to the original" then you're learning the wrong lesson.

Yes, you attributed. But you very deliberately copied the article and posted it as your own work. You can't even say that you forgot to add quote marks as the text was slightly altered - evidently to give you an "out" if anyone accused you of direct copying.

Your threats afterward made things worse - much worse. Not understanding plagiarism (go look up the dictionary, or Wikipedia already!) whilst being an edito of a publication just makes this bad thing horrendous.

Make a full apology. Don't do it again.

Zee, I think it's pretty ridiculous that you're even getting the slightest bit annoyed about this. Needless to say, we'll be saying well clear of anything your are involved with in future. http://notes.unwieldy.net/post/23049725899/plagiarism
